NANFA-- Keeping the crayfish at home

One other thing that keeps our little Maryland stream crayfish from
wandering. They're afraid of mottled sculpins, and won't poke their heads
out from under a rock pile if a big sculpin is around. My sculpin used to
stalk the crayfish--even though they were far too big for him to swallow.

Sculpin like to jam the largest fish possible down their throats and choke
to death. Who knows--if not for the rock piles, they might have tried that
with a crayfish.
