Echinoids (Sea Urchins)

The Echinoids possess a rigid, globular skeleton made up of columns of thin, calcite plates (ambulacrals and interambulacrals). The plates known as ambulacrals have small pores for tube feet. All plates have swollen tubercles for the ball-and-socket articulation of spines, which are used for defence and some-times for walking. Regular Echinoids, which forage on the sea bed show radial symmetry; irregular Echinoids, which usually burrow in soft sea beds, show bilateral symmetry.


This Encope sea urchin is from Mexico and dates from the Pliocene Period
