Abralia trigonura is a species of enoploteuthid cephalopod found in the Pacific Ocean in the mesopelagic zone. Females reach a mantle length of 31–35 mm compared to males at 23–27 mm at maturity. Females spawn in batches of 290–430 small eggs, 0.9 mm in length. The paralarvae stage lasts about 40 days before shifting to adult mode. Male spermatophores are relatively small at 7 mm in length. It migrates to the upper water column to feed at night.

Abralia trigonura ( Dutch; Flemish )

provided by wikipedia NL

Abralia trigonura is een soort in de taxonomische indeling van de inktvissen, een klasse dieren die tot de stam der weekdieren (Mollusca) behoort. De inktvis komt enkel in zout water voor en is in staat om van kleur te veranderen. Hij beweegt zich voort door water in zijn mantel te pompen en het er via de sifon weer krachtig uit te persen. De inktvis is een carnivoor en zijn voedsel bestaat voornamelijk uit vis, krabben, kreeften en weekdieren die ze met de zuignappen op hun grijparmen vangen.

De inktvis komt uit het geslacht Abralia en behoort tot de familie Enoploteuthidae. Abralia trigonura werd in 1913 beschreven door Berry.[1]
