4. Echinodermata: “ Spiny Skinned” Sea Stars, Sea Lillies, Sea Urchins p

5. Phylum Echinodermata Adults have pentaradial symmetry
Larvae are bilaterally symmetrical
Internal skeleton made of calcium plates
Special Fluid filled System (water vascular system)

6. Phylum Echinodermata
Endoskeleton : calcium-rich endoskeleton composed of plates called ossicles
Five-Part Radial Symmetry : larvae are bilateral, as grow into adults, develop pentaradial symmetry

7. Phylum Echinodermata
Water-vascular System : a water filled system of interconnected canals of tiny hollow tube feet.
Tube Feet act as tiny legs used to move, grip and manipulate
Walls of tube feet also used for gas exchange and waste excretion

8. Phylum Echinodermata
Circulation & Respiration: Body cavity, or coelom, functions as a simple circulatory and respiratory system

Platyhelminthes- move with intent, bilateral symmetry, first hunters, hermaphrodites
Nematoda- one way digestion, separate sexes
Annelida- first circulatory system, bilateral, first central nervous system
Mollusca- first visceral mass, foot, mantle,
Arthropoda- segmented legs and body, exoskeleton
Echinodermata- pentaradial, only found in ocean
