Answer 2

Crayfish are one of those bottom of the food chain type critters. They feed on the algea growing on the rocky bottom of streams and rivers, which is where they get their shelter too. They get eaten by predators such as fish and birds and man. Up in the north though, I've got to tell you, those crayfish don't taste as good as the ones from the southern states. I dont know why.. but there ya go.

Answer 3

Crayfish, crawdads or waterbugs, as an old family friend used to call them, are both a food source of many creatures higher on the food chain but are also scavengers feeding on carrion on the bottom of streams, swamps and rivers where them also feed on algae etc. They're in many places you'd least expect them. I have them in my front yard near the road ditch where there is no standing water at all. Just underground springs and streams and ft tall mounds of mud they push up from their tunnels.

Answer 4

They hang out on the muddy bottom of the river and scavenge so they are kinda like the fresh water custodians.
