Habitat and Ecology [top]

Habitat and Ecology:This is a bathydemersal species, it is found on continental slope and rise between temperatures of 4-12°C (Merrett 1990). It is usually solitary, but it probably forms occasional aggregates.

Within the northwestern sector of the Mediterranean Sea, this species appeared starting below 700 m, its relative abundance and biomass increased progressively going deeper. It reaches his maximum between 1,500-2,000m (Morales-Nin et al. 1996).

It feeds on mysids and benthopelagic copepods. The most important food items are benthopelagic planktonic calanoid copepods. In the Catalan Sea, juveniles are found between 1,800-2,250 m, and are recorded to feed secondary on benthic tanaidaceans, whereas for the adults, mysids are secondary. At other depths, calanoid copepods are consumed almost exclusively. Adults ingest larger amounts and sizes of prey than juveniles (Carrasson and Matallanas 2001). It is synchronously hermaphroditic (Sulak 1984).

In the Ionian Sea, this species is found between 800-3,300 m (D'Onghia et al. 2004).

Threats [top]

Major Threat(s): This species is not commercially exploited. No major threats are known.

Conservation Actions [top]

Conservation Actions: Trawling is banned below 1,000 m in European waters in the Mediterranean Sea. This species may be present in Marine Protected Areas that occur within its distribution.
