Sea Stars

Sea StarsSea stars are composed of a central disc from which arms sprout in radial symmetry. Most starfish have five arms, however some have more or less; in fact some starfish can have different numbers of arms even within one species.

The mouth is located underneath the sea star on the oral or ventral surface, while the anus is located on the top of the animal. The spiny upper surface covering the species is called the aboral or dorsal surface. On the aboral surface there is a structure called the madreporite, which acts as a water filter and supplies the sea star's water vascular system with water to move.

Additional parts like cribriform organs present exclusively in Porcellanasteridae are used to generate current in the burrows made by these infaunal sea stars.

Sea Urchins (Preserved)

Sea Urchins (Preserved)

Echinoderms (Phylum Echinodermata, from the Greek for spiny skin) are a phylum of marine animals found at all depths.

This phylum appeared in the early Cambrian Period and contains about 7,000 living species and 13,000 extinct ones. Five or six classes (six counting Concentricycloidea) are alive today:

  • Asteroidea (asteroids, starfish, or sea stars): about 1,500 species that capture prey for their own food.
  • Concentricycloidea (sea daisies), notable for their unique water vascular system; two species; recently merged into Asteroidea.
  • Crinoidea (crinoids, feather stars or sea lilies): about 600 species that are suspension feeders.
  • Echinoidea (echinoids, sea urchins and sand dollars): notable for their movable spines; about 1,000 species.
  • Holothuroidea (sea cucumbers): elongated animals resembling slugs; about 1,000 species.
  • Ophiuroidea (brittle stars and basket stars), the physically largest of echinoderms; about 1,500 species
