[citation needed] The pools of spring meltwater, where they live and eat, begin to dry up as early as mid-May, and the frogs disappear into hibernation below the winter frost line. [ citation needed ] With unusually strong forelegs for its size, the Illinois chorus frog is described as the only frog that uses a breast stroke motion to dig its ...
Pig frogs are important members of their ecosystem, helping to control the populations of the insects and other small animals that they eat. They play a vital role in maintaining the balance of their wetland habitats. The percentage of Pig frogs' prey items varies throughout the year, most likely due to the availability of resources. [4]
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]
Food poisoning, also known as foodborne illness, is a common sickness caused by swallowing food or liquids that contain harmful bacteria, viruses or parasites, and sometimes even chemicals.
The eyes assist in the swallowing of food as they can be retracted through holes in the skull and help push food down the throat. [54] [76] The food then moves through the oesophagus into the stomach where digestive enzymes are added and it is churned up. It then proceeds to the small intestine (duodenum and ileum) where most digestion occurs.

Small or sluggish frogs can be kept in 60 x 30 x 30 cm terrariums; the highly active dendrobatids are an exception as they like to climb; dendrobatids generally need a terrarium of about 1 m x 60 cm x 60 cm. Large frogs, on the other hand, may need a terrarium measuring 1 m in each direction.
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 ...
