Crustaceans and Echinoderms

Differences in Crustaceans and Echinoderms:
-Echinoderms have a spiky skin with an endoskeleton, while Crustaceans have a hard outer skeleton, Exoskeleton.
-Crustaceans molt, which means when they grow and when their about to shed their exoskeleton they reatian extra water to break the old exoskelton for the new one to harden. Since Endoskeletons, have their skeleton grow with them you often find 'tests' left on the beach when they die.
-Echinoderms have radial symmetry, while Crustations have Bilateral symmetry.

Simularities in Crustaceans and Echinoderms:
- The only simularity is that the Echinoderm's larvae has Bilateral symmetry, just like the Crustaceans.

This European lobster, Homarus gammarus, entered a Clive Brown lobster pot off the south coast of Guernsey on the 17 November 1998. What makes this lobster so unusual is that it is a double-crusher clawed lobster. Nearly all lobsters have one crusher claw and one pincer claw. Double-crusher clawed lobsters are rarer than double-pincer clawed lobsters. File No. 35-252 ©RLLord fishinfo@guernsey.net
