Frogs are extremely efficient at converting what they eat into body mass. They are an important food source for predators and part of the food web dynamics of many of the world's ecosystems. The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats.
For example, the same study had shown that in certain parts of Illinois that are more industrialized and had organochlorine peptides there was a larger proportion of intersex frogs. In the case of Illinois, this was in the northeast. However, more environmentally friendly regions, like southern Illinois, had a more diverse frog population. [22]
A 2011 paper raised animal welfare concerns over methods such as live removal of legs and methods of hunting, recommending that countries of origin "establish humane standards to govern the capture, handling, packaging and export of live frogs and for the capture, handling, killing, and processing of frogs used for food to minimize animal ...
Pig frogs are opportunistic feeders and will eat a wide variety of prey, including insects, worms, and small vertebrates. Their primary diet is crawfish, but like most bullfrogs, they will consume almost anything they can swallow, including insects, fish, and other frogs. They are known to feed on beetles, dragonflies, crayfish, and other ...
The diet of Cope's gray treefrog primarily consists of insects such as moths, mites, spiders, plant lice, and harvestmen. Snails have also been observed as a food source. Like most frogs, Dryophytes chrysocelis is an opportunistic feeder and may also eat smaller frogs, including other treefrogs. [24]
The Illinois chorus frogs' preferred habitat in Arkansas includes the patch of sandy wetland soil surrounding Stuttgart, Arkansas where rice is grown. However, the invention of laser land-levelling , and its use by rice paddy operators, has eliminated 61% of the subspecies' range in this southern state.
Ceratophrys is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pacman frogs due to their characteristic round shape, horned brows, and large mouth, reminiscent of the video game character Pac-Man.
Pickerel frogs have varied habitats, the northern populations prefer to live near cold, clear water. They prefer rocky ravines, bogs and meadow streams, but can be found around lakes and rivers that are heavily wooded. In a study on amphibians in Canada, pickerel frogs were negatively associated with young forest stands. [6]
