Spiny Skin

Summary of phyla characteristics Where do they live: Marine What kind of symmetry do they have: Adult – radial Larval – bilateral List 5 classes and give examples of each: Crinoidea- sea lily Ophiuroidea – brittle star Echinoidea – sand dollar, sea urchin Holothuroidea – sea cucumber Asteroidea – sea star

Body Plan: Bilateral symmetrical larvae develop into radially symmetrical adults Deuterostomes – embryonic development in which the 1 st opening in the gastrula (embryo) is the anus. Most have pentaradial symmetry, body parts extend from the center along five spokes Endoskeleton made of calcium carbonate plates known as ossicles which makes up spiny skin. Water vascular system – network of water-filled canals used for oxygen, nutrient circulation. Tube feet – using for movement, feeding, respiration and excretion.

How do they reproduce: Separate sexes Sexual reproduction; most have external reproduction Regeneration occurs in some species

How does it get nutrients: Complete digestive system Some species eject their stomachs to capture prey and bring back into cavity for digestion. This allows capturing of larger prey.

Important vocabulary: Pentaradial – body parts extend from center along five spokes. Deuterostome – embryonic development in which the 1 st opening in gastrula (embryo) becomes the anus. Water vascular system – network of water-filled canals used for digestion, respiration, reproduction. Ossicles – endoskeleton composed of calcium carbonate plates Tube feet – movable extensions of water-vascular system which aid in movement, feeding, respiration and excretion.
