The skin fragments that were found in their stomach are an indication that these frogs commit cannibalism or eat their own skin which is common among amphibians. Based on these results, P. pipa is an ambush predator that will opportunistically eat anything that falls into the water or that it may encounter when occasionally foraging on land.
In some states, breaking the skin while catching them is illegal, and either grasping gigs or hand captures are used. Like most frogs, the hind legs of the bullfrog are the only parts generally eaten. When cooked, they resemble small chicken drumsticks, have a similar flavor and texture and can be prepared in similar ways. [49]
African clawed frogs are fully aquatic and will rarely leave the water except to migrate to new water bodies during droughts or other disturbances. Clawed frogs have powerful legs that help them move quickly both underwater and on land. Feral clawed frogs in South Wales have been found to travel up to 2 kilometres (1.2 mi) between locations.

Many frogs are able to absorb water and oxygen directly through the skin, especially around the pelvic area, but the permeability of a frog's skin can also result in water loss. Glands located all over the body exude mucus which helps keep the skin moist and reduces evaporation.
The mountain chicken is one of the largest frogs in the world, the largest in its family Leptodactylidae and the largest frog native to the Caribbean. It can reach 1 kg (2.2 lb) in weight and up to 22 cm (8.7 in) in snout–to– vent length, although a more typical adult size is 17–18 cm (6.7–7.1 in).
Gizzard of a chicken. The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including archosaurs (birds and other dinosaurs, crocodiles, alligators, pterosaurs), earthworms, some gastropods, some fish, and some crustaceans.
The population of the mountain chicken frog, once abundant in the Caribbean, has dropped by over 99% in 20 years due to a deadly fungal disease.
A gastrolith, also called a stomach stone or gizzard stone, is a rock held inside a gastrointestinal tract. Gastroliths in some species are retained in the muscular gizzard and used to grind food in animals lacking suitable grinding teeth .
