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

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

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

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

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

Phylum Echinodermata Class Asteroidea- Sea Stars NOT STAR FISH

Phylum Echinodermata Class Echinoidea- Sea Urchins, Sand Dollars

Phylum Echinodermata Class Ophiuridae – Brittle stars Basket Stars

Phylum Echinodermata Class Crinoidea Feather Stars Sea Lillies

Phylum Echinodermata Class Holothuroidea Sea Cucumber

The Shape of life: “Ultimate Animals” What are the common names of 4 major echinoderms? How do sea stars walk and grab? What is the term that describes how an animal grows new replacement for lost body parts? How are cnidarians and echinoderms similar? How do sea stars feed on mussels? What two structures are scattered between the spines of sea stars? How can you investigate animals that don’t seem to move? How does a water-vascular system work? How can a sea star be flexible and then suddenly become rigid as a rock? Advantages and disadvantages of extrusible stomach? What are the benefits of being headless and not bilateral?

Warm-up 04/29 List the EightPhyla we have covered and one UNIQUE characteristic of each. Porifera- filter feeders, asymmetrical, specialized cells Cnidaria- stinging cells, radial symmetry, first to move 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
