Integumentary system

Whale Shark (Rhincodon typus) has the toughest and thickest skin of all the animals in the world. It reaches up to 14 cm of thick; whale shark is pale on the underside and dark gray-brown color with white spots on the top. This can serve as a camouflage looking up or down the sea for shark’s preys (SRI, 2008). As all the other Chondrichtyes, Whale Shark skin is covered with little cartilaginous tooth-like structures, this are dermal placoid scales arranged …show more content…

Bullfrogs as most of the other frogs and toads, are faced with an unusual locomotory challenge. They have to swim and jump using primary the hind limbs. The foot possess five rays and hand posses fore rays. Hind 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 exchange: 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 respire 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 will eat just about any animal they can swallow. These include: insects, crayfish, worms, minnows, other frogs (even Bullfrogs), small turtles, snakes, baby 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 frog’s sticky tongue, is diced by tooth-like structures in the mouth. The food
