Squid

Sepioteuthis lessoniana

About

Sepioteuthis lessoniana, commonly called the bigfin reef squid, tiger squid, glitter squid, oval squid or northern calamari, is a species complex in the loliginid squid family and one of three currently recognised species in the genus Sepioteuthis. Studies from 1993 onward suggest that bigfin reef squids may in fact comprise several very similar, closely related cryptic species.

Family
Loliginidae
Avg size
20-40 cm
Habitat
This is a neritic, warm-water squid usually found between the surface and 100 m (328 ft) deep. It tends to stay close to shore near rocks and reefs, is somewhat more active at night, and moves into deeper water or seeks cover during the day; large numbers of juveniles often hide beneath floating driftwood. The most widespread member of its genus, it occurs in the temperate and tropical Indian Ocean and western Pacific.
Behaviour
Bigfin reef squids are close relatives of the Caribbean reef squid, which is known for complex social interactions, and they likewise perform elaborate mating displays. They show both schooling and shoaling, with very young animals staying together (shoaling) without yet swimming in parallel (schooling). Unlike most squids they are rarely cannibalistic, so shoals can mix animals of different sizes without larger members attacking the smaller ones.
