Blind White Crayfish

Crayfish are an old group. They've been around a long time. There are around 41, 42 species of blind, white crayfishes. They may look very spindly and very dainty and weak, but in reality these things are pretty tough. The local streams will have crayfishes that live two and a half to three years maximum, that's their life history. But blind crayfishes kick it up to 50, 60, 70 years, or more. So that longevity is in response to moving underground into that type of environment.
