Habitat and Ecology

Mature males, as demonstrated by the presence of spermatophores, at only 19-22 mm in mantle length and females that attain mantle lengths of 22-26 mm make it one of the smallest species in the genus (Okutani 1983). As well as females attaining slightly larger body sizes, this species also appears to show sexual dimorphism in the number of arm hooks (Okutani 1983). Enoploteuthids generally 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
There is very little known about Abralia marisarabica, and this lack of information makes it impossible to make an accurate assessment of its extinction risk. We therefore list this species as Data Deficient. 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 marisarabica

Abralia marisarabica is a species of enoploteuthid cephalopod that is endemic to the Arabian Sea. It may also be present in the Seychelles. It is one of the smallest Abralia species, growing to 19–22 mm (males) and 22–26 mm (females) in mantle lengths. There appears to be sexual dimorphism in the number of arm hooks present.
