Crayfish or crawdad

Cambaridae sp.

Description:

The greatest diversity of crayfish species is found in southeastern North America, with over 330 species in nine genera, all in the family Cambaridae. A further genus of astacid crayfish is found in the Pacific Northwest and the headwaters of some rivers east of the Continental Divide. Many crayfish are also found in lowland areas where the water is abundant in calcium, and oxygen rises from underground springs. Crayfish were introduced purposely into a few Arizona reservoirs and other bodies of water decades ago, primarily as a food source for sport fish. They have since dispersed beyond those original sites.

Habitat:

One of the black bayous surrounding Reelfoot Lake, Tennessee

Notes:

We saw many of these & also many raccoon tracks & empty shells so it seems that crawfish make up much of the diet o the local raccoons.
