Habitat and Ecology

This species is possibly either a mesopelagic-boundary species like other members of its genus and/or associated with the sea floor (Tsuchiya 2009). It may also spawn seasonally in the East China Sea since large numbers of spent individuals are collected in October from this region (Tsuchiya 2009). Members of the Enoploteuthidae family occur in mid-depths in the ocean and occasionally over the continental shelf (Norman 2003). They undergo diel vertical migrations, rising into the upper water column at night to feed (Norman 2003). Females spawn small eggs (0.9 and 1.5 mm in diameter depending on species, Young et al. 1992) individually into gelatinous strings (Norman 2003).

Justification
Little is known about Abralia multihamata, but it occurs in areas and depths where there is considerable fishing effort. We therefore consider it Data Deficient. Furthermore, the taxonomic relationship between this species and A. spaercki needs resolving before this species can be properly assessed. Further research is recommended in order to determine the precise distribution, population dynamics, life history and ecology, and potential threat processes affecting this species.

Abralia multihamata

Abralia multihamata is a species of enoploteuthid cephalopod native to the waters of the East China Sea, Sea of Japan and Sagami Bay. The taxonomic relationship between A. multihamata and A. spaercki needs to be resolved. It may spawn in the East China Sea, as large numbers of spent individuals are collected there in October.
