Sea Urchin 2″ – 3″

Product Description

Sea Urchins are small, spiny, globular animals which, with their close kin, such as Sand Dollars, constitute the class Echinoidea. About 950 species of echinoids inhabit all oceans from the intertidal to 5000 m deep. The shell, or “test”, of sea urchins is round and spiny, typically from 3 to 10 cm (1.2 to 3.9 in) across. Common colors include black and dull shades of green, olive, brown, purple, blue, and red. Sea urchins move slowly, and feed on mostly algae.
