It eye socketes up to 14 cm of thick behemoth chisel is pale on the have the st argumentsside and dark gray- brownness color with white spots on the top. This tramp serve as a camouflage sounding up or down the ocean for sharks forgos (SRI, 2008).As wholly the former(a) Chondrichtyes, Whale Shark skin is covered with little cartilaginous tooth-like structures, this be dermal placoid scales arranged to reduce the turbulence of peeing flowing a big the carcass go on during swimming (Hickman, 2006). Whale shark master(prenominal)tains internal salt concentrations lower than ocean weewee by pumping salt turn up finished rectal g shoot downs and kidneys. Sharks retain urea dissolved in their organic structure fluids. They too kindle Trimethylamine oxide (TMAO) use to cling to their proteins from denaturation by urea run by products.Retention of this organic solutes in their personate fluids makes their osmolality slightly hypertonic to sea water (Hickman, 2008) Whale Sharks ar ect new(prenominal)mic this room that their eubstance temperature is similar to the surroundings. They whitethorn regulate their remains temperature by behavioral mechanism such as spending time in warmer surface water (Thumbs, 2012). Musculo-Skeletal carcass As menti geniusd, Whale Shark is an elasmobranch the skeleton of this animal is make come to the fore of cartilage instead of bone. This a ache with the big stopr make full with oil champions the shark to float easier an spend less energy on its movement (SRI, 2008).They withal posses an pelvic fins fight downe d by appendicular skeletons, abaxial fins, a medial caudal fin and a median anal retentive fin. The heterocercal drop back in sharks shows that the upturned tail axis tends to produce a fuddle directed downwards behind the center of residue of the fish and thus gives a moment turning the head upwards. This is countered in twain waysby the rotation of the tail along its longitudinal axis during each lateral beat, and through the action of the ventral hypochordal lobe.The embodiment of the tail and the mode of action of the tail in completely sharks so far considered reflects a balance between these three factors, in both of them the net effect creation the production of a forward thrust from the tail that passes directly through the center of balance of the fish (Stewart, Keith and Simanek, Dan, 2012). public discussion System Whale Shark possesses 5 pair of gill slits fixed on the side of their heads (SRI, 2008). Water must continually flow crosswise the gill slits in or der for the shark to breath They do non save gill covers like bony fishes do, so whale shark need to continually swim for constant flow.When water passes over the gill, a dodging of in truth fine beginning vessels takes up the type O from the water. digestive System Whale Shark is a imbue feeder. As it swims with its oral cavity open, masses of water filled with prey enter to its m forthh consisted of 5 large gill arches. After closing its m placeh, shark uses special(a)ized variety meat called gill rakers to filter the nourishment from the water. Basically allthing that does non pass money box the gills is eaten. (SRI, 2008). Preys may include plankton, krill, midget fish and even squid. This shark bottom of the inning transition over 6000 liters of water each our.urinary System Urea and trimethylamine (TMAO) in their blood and tissues help to maintain their osmotic balance. They atomic number 18 without the usual urinary tract, so they concentrate urea in their bl ood and excrete it through their skin (Hickman, 2006). procreative System According to the Shark research institute, counterpart behavior is uncertain. In their article Whale Shark FAQ they state exactly one pregnant egg-producing(prenominal) shark has ever been exani duplicated by scientist Dr. Jennifer V. Schmidt, film director of SRI genetics Program (12). The only pregnant egg-producing(prenominal) caught ontained in her tween womb 307 embryos measuring between 42 and 63 cm in distance, 15 where fully- developed and ready to born. Having this information whale sharks where appoint to fall into the classification of ovoviviparous. This information also suggests that Whale Sharks could be one of the nigh productive live bearing shark species. But it remain unknown why their population is excellent. Sexual maturity in whale sharks may occur until they reach to the mellowest degree 9 meters long which is about 30 eld old. Whale sharks live for about 70 to 800 years. (S RI, 2009) bull capture (genus Rana castabeiana) Kingdom AnimalPhylum Chordate Class Amphibians Order Salientia Family Ranidae Genus Rana Species Rana catesbeiana (Bull salientian) Integumentary system Frog skin is thin and broadly attached to some(prenominal) of the muscles in the body. It is composed the skin is known to be permeable, which means that let the water pass in and out through the skin membrane. Bullfrogs skin is periodically shed as former(a) frogs and toads do. The epidermis of the Bullfrog contains two types of glands mucous glands, which help to protect the frog from dehydration and a large serous of glands that produce watery, toxicant material (Hickman, 2006).Musculo-skeletal system As many contrastivewisewise amphibians bullfrogs live mainly in fresh water, but they can also migrate to separate pounds lakes or reservoirs specially when is rainy or hummed. Bullfrogs have a well-developed endoskeleton do out principle of bone and some cartilage this provide s support for mesomorphic movements (Hickman 2006). Bullfrog tent to develop fast(a) and big muscles used for travelling outside or inside the water. Bullfrogs as most of the other frogs and toads, are faced with an unusual locomotory challenge. They have to swim and jump using primary(a) the hind limbs.The foot possess cardinal rays and hand posses fore rays. back(prenominal) limbs and fore limbs posses a web-like structure to help frog locomotion also in water (Nauwalaerts, Sandra et al, 2007). Respiratory system Bullfrogs as many other amphibians use three respiratory surfaces for gas transpose skin, mouth, and lungs. In bullfrogs lungs are present in adults (Hickman, 2006). On land Bullfrogs breath with their mouths closed. Bullfrogs present a positive lung pressure for breathing (Heckman, 2007). Their throat movements pull air through the nostrils to the lungs. Then breathe out with body contractions.Bullfrogs can also take a breath under the water through the skin using a process called cutaneous gas exchange. They use their skin for oxygen/carbon dioxide exchange (Stinner N, Jerry, and Shoemaker, H. Vaughan, 1987) digestive system Bullfrogs are voracious eaters, and allow eat muchover about any animal they can swallow. These include insects, crayfish, worms, minnows, other frogs (even Bullfrogs), small turn turtles, snakes, featherbed birds, and small mammals. They are most active at night. The frog digestive system, like most other digestive systems, starts in the mouth.Prey, which is sometimes caught by the frogs sticky tongue, is diced by tooth-like structures in the mouth. The nutriment then moves down through the esophagus, into the stomach, where, much like in the shark, the nutrient is softened, broken down somewhat, and stored. From the stomach, food moves into the small intestine, where the most of the chemical digestion (i. e. the pancreas secretes pancreatic juice, the liver secretes bile, etc. ) and nutrient absorption take pla ce. One special attribute of the frog small intestine is that it has villi, small projections that greatly ncrease the surface area of the small intestine, allowing more nutrient absorption. Urinary system The urinary system of Bullfrogs as most of the frogs is the organ system that produces, stores, and eliminates urine. The kidney excretes and re-absorbs electrolytes (e. g. sodium, potassium and calcium) under the influence of local and systemic hormones. pH balance is regulated by the excretion of bound acids and ammonium ions. procreative system Bullfrogs are known to be oviparous and breeding occurs in permanent bodies of water that typically contain thick grows of algae and rooted aquatic plants.Breeding pools usually are rich in aquatic animal action and have a soft mud bottom (Hammerson, Geoffrey A, 1999). They initiate amplexus by making physical contact with an adult male. Amplexus and oviposition generally last from 15 min to 2. 5 hours and occur about midnight. Bullfro gs have found to mate and lay eggs in areas outside the sites defended by calling males. (Hammerson, Geoffrey A, 1999). verdancy sea turtle ( order Chelonia mydas) Kingdom Animalia Phylum Chordata Subphylum Vertebrata Class Reptilia Order Testudines (turtles and tortoises)? Family Cheloniidae (true sea turtles)? Genus Chelonia?Species Chelonia mydas Integumentary System Green sea turtles, as all the turtles species have evolved a bony outer shell, which protects them from predators. This shell covers twain abaxial and ventral surfaces and it is consider the most highly developed preventive armor of any vertebrate species to have ever lived. (Green sea Turtles, 2001). The dorsal portion of the shell is known as carapace and it is covered with a large scale-like structures called scutes. The ventral portion of the shell is known as the plastron. This two structures are connected by hard shelled plates called lateral bridges.A difference of land turtles and tortoises, sea turtles a re not able to retract their heads into their shells, and they heads remain out at all times (Green sea turtles, 2001) Green sea turtles are ectothermic animals, which means that they regulate their internal temperature from their environment, this also explains why this turtles live in warm temperatures. Chelonia mydas maintain homeostasis using a vary gland called salt gland it helps them controlling their internal environment and it is placed just behind each eye. Using this gland they excrete the additional of salt levels in blood in forms of tears. Green Sea Turtles, 2001). Musculo-skeletal system The skeleton is composed of bones and cartilages. Typically, it is divided into 3 main parts the skull, axial skeleton and appendicular skeleton in sea turtles, each of these bony groups is a composite of several structures. The skull includes the braincase, jaws, and hyoid implement the axial skeleton is composed of the carapace, vertebrae, and ribs and the derivatives of the r ibs. The plastron is a composite including derivatives of the axial and appendicular skeleton (ventral ribs plus shoulder elements).The appendicular skeleton includes the flippers, hind limbs, and their livelihood structures (the pectoral and pelvic girdles). (Wyneken, 2001. ) Sea turtles are interesting because they have very highly evolved flippers to help them propel through the water. In addition to being able to propel themselves through the water, the sea turtles use their flippers to climb up steep, rocky shores and can use their flippers to evade all sorts of different predators of the sea turtles. While sea turtles all have the same basic anatomy, thither are some things that set some species of sea urtles apart from other sea turtles. For example, Green sea turtles have prefrontal scales on the head, a differing number of scutes on the carapace, and the type of inframarginal scutes that appear on the pastron. (Wtbeken, 2001. ) Respiratory system The sea turtle petitions a respiratory system that is able to support it through diverse depths and distances. Due to sea turtless excessive breath-hold, the respiratory system must be able to compensate for time elapsed without exit. When exhalation does occur, it is brief. The main component that bears the respiratory weightiness is essentially the lung.The lung, functions as the study oxygen store and can supply sufficient oxygen for most routine dives (up to 20 mins) to be aerobic (Lutz, 1985). Moreover, the lung almost carries the complete cargo of respiration in the sea turtle. The respiratory properties of sea turtle blood are particularly well suited to lung-tissue transport during routine brethhold periods, live on prolonged dives of at least three hours by having a high anaerobic capacity (Lutz, 1985). A difference of the amphibians, turtles posses a negative lung preassure. digestive systemGreen sea turtles, Chelonia mydas, get their name from the color of their body fat, which is blue jet from the algae or limu they eat. Adult green sea turtles are herbivores, moment that they eat only plants, and therefore do not pose a threat to any other marine animals. Juvenile green sea turtles on the other hand are carnivorous. Their diet consists of jellyfish and other invertebrates (Green sea turtles, 2001). Although the carapaces of green sea turtles are mostly dark brown in color, they can be covered with patches of algae on which fishes in turn feed (Green sea turtles, 2001).This particular relationship of the fish eating algae off the turtles shell would be considered a form of mutualism. Urinary System The excretory system of the turtle is responsible for removing harmful negates from the turtles body and blood. The kidney of the turtle performs the blood filtering process and the wastes are then sent to the vesica as urine. In sea turtles the kidneys are also aided by the salt gland to get rid of the excess salt in the sea water (Green Sea Turtles, 2001). The vesic a is the storage place of the urine. From the bladder the urine goes to the cloaca, which is where urine leaves the body.The cloaca is also used to take in oxygen and other nutrients in sea turtles when they reach critical levels. Reproductive System Although green sea turtles live most of their lives in the ocean, adult distaffs must return to land in order to lay their eggs. Biologists hope that nesting female turtles return to the same beach where they were born. Hawaiis green sea turtles migrate as far as 800 miles from their feeding areas along the coasts of the main Hawaiian islands to their nesting beaches in the Northwestern Hawaiian islands (Green Sea Turtles, 2001).Males accompany the females during the migration, which usually occurs in the late spring, and mate with them off the shores of the nesting beaches. Females do not mate each year, but when they do, they come ashore often- as many as five times every 15 twenty-four hourss to make nests in the spine and lay eggs. Green sea turtles nest only at night. The female must pull herself out of the water and all the way to the run dry sand of the upper beach using only her front flippers. This is a difficult task as her front limbs have been modified into highly effective swimming flippers, and do not support the bulk of her weight in the sand.After placing the eggs female basically has completed her parenting job, then she returns to the sea leaving her youngs to fend for them-selves. Unfortunately, not all of the hatchlings reach the ocean. Many are snatched up by hungry crabs and other predators along the way or become lost and die. In addition, some are eaten by sharks and other carnivorous fishes while at sea. still a few baby turtles from each nest will move into adulthood. catamount (Panthera Onca) Kingdom Animalia Phylum Chordata SubPhylum Vertebrata Class Mamalia Subclass Theria Infraclass EutheriaOrder order Carnivora Suborder Feliformia Family Felidae Subfamily Pantherinae Genus Panthera Species Panthera onca Integumentary system Mammals bodies are covered by hairs, tegumentary features that contribute to the regulation of body temperature. In the skin there are a quantity of sweat glands and soapy or oil glands that help to keep the skin in total health by lubricating it and eliminating toxic byproducts through the sweat. In addition to this excreting function, the sweat contributes to thermo-regulation, cooling the surface through evaporation.In addition to hairs, the skin grows other structures, such as nails, claws or hooves as well as the horns and pachydermal foot pads of certain mammals. Heterodontia is characteristic of mammals, that is to say that they have teeth of different structure, as opposed to homodontia, in which all the teeth are alike. Musculo-skeletal system The jaguar is a large and muscular animal that has a heavier and sturdier body than that of a Leopard. They have a large, broad head with jaws so well-set that they are said to have the most powerful bite of all the worlds Cats. Jaguar, 2008). They are also fast runners, but they get tired quickly. They can also climb very well and are good swimmers. (Felines, 2002) The cougars skeleton is not so different from the adult male skeleton. Jaguars have more bones and many are identical to those in the human being. They have have 13 ribs humans have 12. They also do have clavicles but unlike humans, they are not attached to other bones. The outside of a bone, the cortex, is composed of minerals and protein and gives the bone its rigidity. Inside the bone is the kernel cavity that produces red blood cells.Jaguars muscles are tough and well-coordinated and help to make the animal an agile hunter. Basically, jaguars muscles are designed for walking, running, leaping, and twisting. Their muscular control and skeletal flexibility enable it to right its body during a fall with incredible speeda trick that is whimsical to the family felidae. Respiratory System Th e respiratory system functions primarily to transfer oxygen from the air to the blood and to remove carbon dioxide from the blood and carry it out of the body into the air. Oxygen is vital to the bodys maintenance.Carbon dioxide is a waste product of the maintenance process. Jaguar breathes in air through its schnozzle and mouth. The nose and mouth join to form the pharynx. The trachea is a organ pipe that extends from the pharynx to the lungs. The epiglottis covers the trachea when swallowing occurs to prevent food and water from entering the lungs. At the lungs the trachea branches into small tubes called bronchi or bronchial tubes. The bronchi divide into smaller and smaller bronchioles until they become dead end sacs called alveoli. It is in the alveoli where the actual exchange of oxygen and carbon dioxide occur.Digestive system The jaguar is a carnivore. It hunts mostly at night. Its prey includes capybara, peccaries, deer, large ground birds, fish, snakes, turtles and rabb its. It will also eat livestock like horses, cows and sheep. The jaguar hunts mostly on the ground, but it sometimes climbs a tree and pounces on its prey from above. The jaguar has very powerful jaws and slap-up teeth and usually kills its prey with one crushing bite to the skull. ( Jaguar, 2008) Jaguars digestive system is comprised of the nourishing canal and accessory glands.The alimentary canal consists of the lips, mouth, teeth, tongue, esophagus, stomach, small intestine, large intestine, and anus. The accessory glands are the liver, pancreas, and the salivary glands. any the variety meat mildew to process the food a cat eats. The intestines work to extract and absorb the nutrients and eliminate the wastes. (Foss, A. Michael, et al, 2008) Urinary System The important organs of the cats urinary system are the kidneys, ureters, bladder, and urethra. The kidneys are located on either side of the body in the lumbar piece (between ribs and pelvis).Blood is filtered through th e kidneys and the liquid waste product is called urine. Urine is passed through the ureters to the bladder where it is stored. The urine is then discharged through the urethra, a tube connecting the bladder to the exterior of the body. (Foss, A. Michael, et al, 2008) Reproductive system Despite the fact that most Jaguar cubs are generally born between the months of December and March, it is not fantastic for them to be born at other times of the year. During the mating season, the female Jaguar will use loud vocal calls to attract a male into her territory. Female Jaguars typically give birth to two or three cubs.Once their cubs are born however, the female Jaguar will not tolerate the male in her territory as she becomes very custodial of her young at this stage. Jaguar cubs are born blind and crystalise their sight after about two weeks. They are weaned by their mother when they are around 3 months old, although the cubs will rely on their mother to hunt and provide for them un til they are about 6 months old. At 6 months, the Jaguar cubs will then start to accompany the female jaguar on hunts but will not venture out on their own until they are one or two years old and have established a territory for themselves. Jaguar, 2008) Scarlet Macaw (Ara macao) Kingdon Animalia Phylum Chordata Subphylum Vertebrata Class Psittaciformes Family Pisttacinae Genus Ara Lacepede, 1799 Species Ara macao slipstream Ara macao cyanopterus Integumentary system Scarlet macaws are brightly sullen birds with feathers ranging in color bands from scarlet on their head and shoulders, to yellow on their back and mid wing feathers and blue on the wing tips and tail feathers. The face has short white feathers. This area surrounds the light yellow glowering eyes. The long, thick beak is light on the top and dark fateful on the bottom.The legs and feet are also black (David, 2003) gentlewomans are endothermal, or warm-blooded. That means they have an internal furnace, fueled by foo d, that generates heat and allows them to keep their bodies at a constant temperature, even though the temperature of their environment changes. Birds are also able to regulate their body temperature by conserving or losing heat through a variety of ways - feathers help retain heat, while trousering helps get rid of heat. (Bird Life, 2008) Musculo-skeletal system Macaws are the largest parrots in the world the body of the scarlet macaw from beak to tail can be as long as 33 inches.This beautiful macaw has a creamy white, almost unfledged face, with bright red plumage covering most of its body, wings and long tail. Brilliant blue and yellow feathers also adorn the lower wings. The birds strong beak is adapted to breaking hard nuts found in the rainforest. (David, 2003) Respiratory system The high metabolism and athletic life-style of birds require a great deal of oxygen. Four organs work in concert to carry oxygen to the cells nostrils, trachea, lungs, and air sacs. With each brea th, air moves through the nostrils, down the trachea and into the lungs and air sacs. From the lungs, xygen passes into the bloodstream and then to the body cells. The air that passes into the air sacs cools the internal organs and helps maintain body temperature. Nearly all of the air in the lungs is replaced with each breath. When flying, birds require ten to twenty times more oxygen than at rest. To supply the extra oxygen, birds increase their breathing rates. (Bird Life, 2008) Digestive system Wild Scarlet Macaws mostly eat fruits and seeds, including large, hard seeds. like other parrots, they are seed predators, they destroy the seeds that they eat and do not disperse them. Some macaws are sometimes seen eating clay from river banks. Bird Life, 2008 Since birds have no teeth, the digestive system must grind up food so that the energy stored in it can be used. A hollow digestive tube extends from the mouth through the entire length of the body to an external opening called th e cloaca. The tube is divided into the throat (pharynx), esophagus, stomach, small intestine, and large intestine. Urinary system The urinary system of birds is different from mammals, as birds produce both urine and urates. The kidneys possess two different types of nephrons, the units that filter the blood to remove toxins and products of metabolism.Birds cannot concentrate their urine as well as mammals can. Birds also are uricotelic, meaning that they excrete the end product of due north metabolism as uric acid, which is made in the liver and they excreted from the blood. uric acid is the creamy white portion of the dropping. Urine is the clear portion. The pot constitute the third portion of a dropping, and this consists of the solid portion, usually brown or green, depending on what the bird has been eating. A bird is able to cause independently of defecating, or passing feces, but most of the time, the bird will pass urine, urates and feces at the same time. Bird Life 2008 ) Reproductive system Like most parrots, the female Scarlet Macaw lays 2 to 4 white eggs in a tree cavity. The young hatch after 24 to 25 days. They fledge about 105 days later and leave their parents a year later. (bird life, 2008) The scarlet macaw protects its baby by staying in the nest with the baby or babies and being aware of any type of danger. It pinches predators with its beak and screams noises for help when a predator wants to eat the baby and/ or female. The female stays with the baby 1-2 years. It stays most of the day and the male fetch food for the baby or babies. Brightsmith, 2004) Works cited Shark Research Institute. Whale Shark FAQ. Dlvingdog productions Inc. Nov 2006.
