The Thursday Channel: Crayfish of Ohio

The International Association of Astacology says: " Crayfish , crawdad , crawfish , yabby , freshwater lobster and mudbug all refer to the same animal. Crayfish and lobsters look similar to one another, and are closely related, but all crayfish live in freshwater, whereas, all lobsters live in saltwater. The smallest crayfish reach only 2 cm (0.8 in) in length, while the largest can exceed 80 cm (31.5 in)! Crayfish eat just about everything, from plants, insects, leaf litter to small fish. Crayfish are very important prey items in stream ecosystems and are the primary food source for many animals including fish, amphibians, reptiles and birds. Crayfish have adapted to all sorts of environments, from streams and lakes to caves and even burrows that they dig to reach the ground water." - https://www.astacology.org/AboutCrayfish.asp?uid=Guest This presentation will be give by zoologist, by Roger F.
