Green Crabs

Green Crab Identification

Green Crabs have 5 spines on each side of their eyes.  Their carapace (shell) is roughly pentagon shaped.  The crabs can be green, brown or red.

Green crabs rarely grow larger than 3 1/4 inches.  The size measured is the width of the crab at the widest part of its carapace – from the tip of one spine to the other.
