Phylum: Echinodermata “spiny”“skin” - (think dermatologist)

Phylum: EchinodermataEchinodermata Very unique phylum of animals Larvae start off with bilateral symmetry Then they switch to radial symmetry - “pentaradial” Oral surface (underneath) Aboral surface (on top) They have an endoskeleton - “ossicles” They have:

Phylum: Echinodermata Examples: 1. Sea Stars - “Common starfish” 5 arms Their appendages will regenerate!regenerate They can autotomize (drop off) their arms! regurgitatingregurgitating their stomach onto prey! They eat by (get ready) They have pedicellariae, little pincer-like claws on the aboral surface They have skin gills on aboral surface for breathing

Phylum: Echinodermata Examples: 2. Sea Urchins / Sand dollars Endoskeleton forms a round rigid “test” They have moveable spurs and pedicellariae Aristotle’s lantern - set of 5 jaws & muscles found inside their mouth (on the bottom side)

Phylum: Echinodermata Examples: 2. Sea Urchins / Sand dollars Aristotle’s lanternAristotle’s lantern - set of 5 jaws & muscles found inside their mouth (on the bottom side)

Phylum: Echinodermata Examples: 3. Sea Cucumbers Lack radial symmetry NOT bilateral either Can range from 6 inches to 6 feet long! Worm-like body: Highly intricate defense: 1) secrete toxins 2) eviscerate - “throws up” internal organs

Phylum: Echinodermata All Echinoderms move with tube feettube feet They use a Water Vascular System: 1. Madreporite 2. Stone canal 3. Ring canal 4. Radial canal 5. Ampullae 6. Tube feet

5 classes of Echinoderms Kingdom: Animalia Phylum: Echinodermata Class: –Asteroidea – “Star” –Crinodea – “Flower form” –Echinodea – “Long spines” –Holothuridae – “Hollow tube” –Ophiuroidea – “Brittle arms”

Foldable Make a foldable comparing the 5 classes of Echinoderms. –1. How they feed –2. How they move –3. How they protect themselves –Blue Books – pages

Classification Classify the pictures in the envelopes into the 5 classes of echinoderms! –Asteroidea – “Star” –Crinodea – “Flower form” –Echinodea – “Long spines” –Holothuridae – “Hollow tube” –Ophiuroidea – “Brittle arms”
