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.

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]
Western chorus frogs live in a variety of different habitats, but areas of more permanent water increase the risk of predation on eggs and/or tadpoles. To compensate for this, chorus frogs stick to mostly ephemeral freshwater areas, such as marshes, river swamps, meadows, grassy pools, and other open areas found in mountains and prairies.
Lithobates clamitans [5] or Rana clamitans, [2] [6] [7] commonly known as the green frog, is a species of frog native to eastern North America. The two subspecies are the bronze frog and the northern green frog. These frogs, as described by their name, typically have varying degrees of green heads.
They then lunge and swallow the prey whole. [8] They feed on other frogs, insects, and snails. [9] Both adults and tadpoles of the species are known to be occasional cannibals. [8] [10] [11] The tadpoles of this species are obligate carnivores that swallow their prey whole. [10]
Wood frogs range from 51 to 70 mm (2.0 to 2.8 in) in length. Females are larger than males. [5] [6] Adult wood frogs are usually brown, tan, or rust-colored, and usually have a dark eye mask. [7] Individual frogs are capable of varying their color; Conant (1958) depicts one individual which was light brown and dark brown at different times.
