Purple+Shore+Crab

The Purple Shore Crab is part of the Phylum Molusca. To be a bit more specific its part of the class Malacostraca. Purple Shore Crabs live on the West coast between Alaska and Baja California. They Mainly have a purple shell but can sometimes turn greenish yellow or reddish brown. They are easily identified when you see the purple spots on their claws. Their diet mainly consists of green algea they scrape off of rocks but they also eat sea lettuce. These crabs can often grow between 2-4 inches in size. When you go down to the beach just lift up a rock and there is a good chance one of these crabs is going to be there.
