Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Males and females attain similar body sizes (21 mm in mantle length). This small species occurs from shallow water to the upper continental slope, although associated with the benthos it has been collected from the water column during the day as well as at night (Reid and Jereb 2005). This species has a light organ (Norman 2003). Mature males have enlarged suckers and a fleshy bulb on the tip of their left first arm (Norman 2003). Off Scotland (Firemore Bay) spawning appears to occur throughout the year with peaks in April and July to August (Reid and Jereb 2005). Members of the subfamily Sepiolinae are bottom living species that typically bury in soft sediments during the day, and emerge at night to feed (Norman 2003).

Justification
Sepiola atlantica has been assessed as Data Deficient because little information is available on fishing take. Although it is not targeted by commercial fisheries, it is probably caught locally and until more data are available the impact of such take cannot be assessed.

Sepiola atlantica

Sepiola atlantica, also known as the Atlantic bobtail, is a species of bobtail squid native to the northeastern Atlantic Ocean (65ºN to 35ºN), from Iceland, the Faroe Islands and western Norway to the Moroccan coast. There is a single record of this species from the Mediterranean Sea.[1]

Both sexes of S. atlantica grow to around 21 mm in mantle length.[1]

The type specimen was collected in the Bay of Biscay and is deposited at the Muséum National d'Histoire Naturelle in Paris.[2]
