Spiny skin Radial symmetry Water vascular system
Form and Function Water vascular- respiration, circulation, movement.Madreporite- connects the ring canal to the outside.
Tube feet- movement. Feeding- sea stars push out stomach and enzymes break down shells. Excretion- cellular through tube feet(ammonia), solid through anus. External fert.
Groups of Echinoderms
Sea Urchins and Sand DollarsLarge solid plates Most eat algae
Brittle Stars Found on coral reefs Can shed an arm to escape Found on coral reefs Can shed an arm to escape Filter feeders
Sea Cucumbers “ Moving pickles” Detritus feeders
Sea Stars Most are carnivores Eat bivalves Can repair themselves
Sea Lilies and Feather StarsFilter feeders Live in the tropics
