This 3D Mathaeus Sea Urchin contains three highly detailed, fully textured 3D models of the plant at different ages.

Clade: Echinodermata Depth: 0 to –8 m.
Distribution: Red Sea to Polynesia
Environment: reef roofs, protected reef slopes
Climate: warm waters

Notes:
Mathaeus Sea Urchin is a frequent inhabitant of the reef. He is to be found on the reef roof and at the upper reef slopes. During the day they hide themselves in holes (scraped by their own) in the coral rocks, before they come out at night to food search. The contrast between the reddish-brown pricks and the white basal ring is salient.
