Description: Gastrosaccus spinifer is an opossum shrimp; these are small, shrimp-like creatures with pinnate legs, a transparent body, remarkable eyes and a broad tail fan. Whereas most opossum shrimps spend their lives swimming freely in the water column, Gastrosaccus spinifer spends a major part of that time buried in the sediment. Consequently, the species is usually associated with the macrobenthos. Gastrosaccus spinifer can reach a length of 21 mm and is characterised by a narrowing of the fifth abdomen segment with a dorsal finger-like ‘spine’ on top. [details]
Distribution: In both periods Gastrosaccus spinifer was found distributed across the entire Belgian part of the North Sea with a relatively high distribution frequency. The maximum density amounted to 130 ind./m2 in the 1976-1986 period and to 1,000 ind./m2 in the 1994-2001 period. [details]
Habitat: Gastrosaccus spinifer is found in a wide range of sediment types. In general, the relative occurrence increases in proportion to the median grain size of the sediment up to a maximum relative occurrence of over 60%, which is reached when the median grain size is 450 to 550 µm. Gastrosaccus spinifer does not display an absolute preference for sediments with a specific mud level. However, the species is absent in sediments with a mud content exceeding 70%. [details]
