Enteroctopus magnificus, also known as the southern giant octopus, is a large octopus in the genus Enteroctopus. It is native to the waters off Namibia and South Africa.

Description

[edit]

E. magnificus bears the distinctive characteristics of the genus Enteroctopus, including longitudinal folds on the body and large, paddle-like papillae. E. magnificus is a large octopus, reaching total lengths of up to 1.8 metres (5 ft 11 in)[1] and a mass of 11.4 kilograms (25 lb).[2]

Range and habitat

[edit]

E. magnificus occurs from Namibia to Port Elizabeth, South Africa. It is found primarily on sand and mud flats from shallow subtidal areas to about 1,000 metres (3,300 ft) depth.[1]

Predators

[edit]

E. magnificus is predated on by the South African fur seal (Arctocephalus pusillus pusillus) and the leafscale gulper shark (Centrophorus squamosus).[2]

Diet

[edit]

Like many octopuses, E. magnificus is a generalist predator. The chief food source for this octopus is the deep-sea portunid crab Bathynectes piperitus. Other major prey items include the Cape hagfish (Myxine capensis), the crab species Pontophilus gracilis, and hermit crabs in the genus Parapagurus.[2]
