TRANSPARENT CRAYFISH -
Caves are some of the darkest places on the planet – even sophisticated light-gathering instruments are unable to register a single photon in the deepest, darkest caves. Under these conditions, creatures including fish, spiders, insects and crayfish have evolved into “troglobites”: animals so precisely adapted to living in darkness that they cannot survive outside cave environments. Under such conditions, neither eyes nor pigmentation are necessary.
