Burrowing crayfish in Ohio belong to one of two genera in the family Cambaridae: Cambarus and Fallicambarus. These land-lobsters are sometimes referred to as Terrestrial Crayfish owing to their lack of a direct connection to bodies of water. However, just like their aquatic cousins, these crayfish use gills to extract oxygen from water. Unlike their water-soaked cousins, burrowing crayfish spend most of their lives on land.
