| Abstract |
The sea urchin Stomopneustes variolaris (Lamarck) is a common inhabitant of rocky shores of Visakhapatnam, East Coast of India. It is common at 0.2 m CD and lower in the infralittoral fringe with abudance of algae. High densities up to 6.4/0.2 sq.m. were noticed in rock pools, crevices , gullies and other protected habitat on shores with severe wave action. The density was lowest (4.7/0.2 sq.m.) where the wave action is low to moderate. Significant aggregations were noticed at shores with pronounced to severe wave action as a response to environmental factors such as wave action water circulation and availability of protected habitats. |
