Description Echinocyamus pusillus is a small sea urchin with an oval, flattened body measuring up to 15 mm long. The calcite skeleton is completely covered with fine short spines and coloured grey to greenish. Specimens become completely green when injured, a characteristic the species shares with some other sea urchin species. [details]

Distribution Echinocyamus pusillus occurred outside the near-coastal zone in both periods. In the 1994-2001 period the species was furthermore observed a number of times in the western coastal zone. Maximum density is 400 ind./m2 (1994-2001 period). [details]

Distribution Echinocyamus pusillus occurred outside the near-coastal zone in both periods. In the 1994-2001 period the species was furthermore observed a number of times in the western coastal zone. Maximum density is 400 ind./m2 (1994-2001 period). [details]

From other sources
Habitat Echinocyamus pusillus has a preference for medium to coarse-grained sand (median grain size: > 200 μm) and reaches an optimum in sediments with a median grain size of 500-550 μm (relative occurrence: 30%). The species furthermore prefers sediments with a low mud content (maximum 10%). [details]
