Common Spider Crab

The Common Spider Crab (Libinia emarginata) is a marine (saltwater) crustacean. It is also known as the Portly Spider Crab or the Nine-Spined Spider Crab. 

The Common Spider Crab is almost triangular in shape with an olive-khaki-green exo-skeleton (shell) called a carapace. The carapace is covered in spines called tubercles. It has 10 orange legs. 

The Common Spider Crab walks forward – unlike most crabs that walk sideways.
