From other sources
Biology E. pusillus has separate sexes and fertilization takes place externally. The breeding season is in the summer months. The larvae are pelagic. They are characterized by a body skeleton forming a basket-like structure (Mortensen, 1927; Fish & Fish, 1989).
E. pusillus is a deposit-feeding clypeasteroid. lts gut content includes sediment, remains of plants and bottom material (detritus), and infauna, especially foraminiferans. E. pusillus is eaten by fish, especially by dab and haddock (Mortensen, 1927; De Ridder & Lawrence, 1982; Fish & Fish, 1989). [details]
Breeding Echinopluteus larva. Summer - autumn [details]
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 It is dominant at the Cleaver Bank and in the south-western part of the Southern Bight. The species is absent from the Wadden Sea, the Delta area, the Voordelta, the Dutch coast and the Oyster Ground. [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]
Habitat In the Dutch sector of the North Sea E. pusillus mainly occurs in the areas between 20 to 30 m of depth, in coarse to medium sand bottoms. [details]
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]
Habitat Known from seamounts and knolls [details]
Morphology E. pusillus has an oval, much flattened test of up to 15 mm in length. The test is covered with fine short spines and is greyish or greenish in colour. On preservation or when hurt it turns green, a character distinctive of all clypeasteroids (Mortensen, 1927; Southward, 1972; Fish & Fish, 1989; Hayward & Ryland, 1990). [details]
