Functional adaptation 1
Li mb s sacri fi ced to escap e p red ators: crab s
The claw and other limbs of a crab assist escape because they can be shed and regenerated.
Maintain physical integrity > Protect from biotic factors > Animals
"In some invertebrates, autotomy can involve the loss of one or more legs. Crabs, for instance, are
famous for sacrificing a claw if attacked by a predator, which they will then regrow. Indeed, they are
willing to lose several of their limbs if necessary to avoid capture, though this willingness decreases
markedly with each successive limb loss, for obvious reasons." (Shuker 2001:132)

Taxon biology 2
You often find shrimp and small crabs swimming in shallow water or on the beach. Larger crabs and
lobsters are found in deeper water. These animals belong to the decapods. There are all kinds of
decapods, some of which are considered a true delicacy, and not just by humans.
