Opisthoteuthis hardyi is a lesser-known octopus species. It was described in 2002 from a male caught off the Shag Rocks, which are far south in the Atlantic Ocean near the Falkland Islands. [3]

The specimen was medium-sized, with a mantle of 45 mm (1.8 in) long. The whole body was 250 mm (9.8 in) long. [4] It had some enlarged suckers, which is typical for male octopuses belonging to Opisthoteuthis . It also had a web connecting its long arms, which is common for cirrate octopuses and some incirrate octopuses. [3]

The specimen was found in the open ocean between 800 m (2,600 ft) and 1,000 m (3,300 ft) deep. [3] However, the true depth range is wider. After 2002, dozens more specimens, likely O. hardyi, were discovered on the Patagonian Shelf from 630–1,390 m (2,070–4,560 ft) deep. [5] [6] [7]

<i>Grimpoteuthis</i> Genus of cephalopods known as the dumbo octopuses

Grimpoteuthis is a genus of pelagic cirrate (finned) octopods known as the dumbo octopuses. The name "dumbo" originates from their resemblance to the title character of Disney's 1941 film Dumbo, having two prominent ear-like fins which extend from the mantle above each eye. There are 17 species recognized in the genus. Prey include crustaceans, bivalves, worms and copepods. The average life span of various Grimpoteuthis species is 3–5 years.

It is known from a single specimen which was collected in the northeastern Atlantic Ocean. It has characteristics which are shared with two other genera, Opisthoteuthis and Grimpoteuthis, but is sufficiently distinctive from either of these to warrant the erection of a new genus.

Opisthoteuthis persephone is a cirrate octopus living south of Australia. In particular, it lives in waters off Tasmania, Victoria, New South Wales, and South Australia. The octopus has been found 270–540 m (885.8–1,771.7 ft) deep. It lives near and directly above the seafloor. S. Stillman Berry was the first to scientifically describe this species after capturing eight specimens while aboard the F.I.S. Endeavour in the early 1910s. In describing O. persephone, Berry called it an "exceedingly interesting octopod".

Opisthoteuthis pluto is a deep-sea cirrate octopus found in the Great Australian Bight south of Australia. They live 270–810 m (890–2,660 ft) below the surface in the bathyal zone. Although their habitat is threatened, it is unclear how the species is affected, if at all. O. pluto is named for the Greek and Roman god of the Underworld.

Opisthoteuthis robsoni, also known as the deep-water umbrella octopus, is a deep-sea octopus living off New Zealand on the Chatham Rise. It has been found from 1,178–1,723 m (3,865–5,653 ft) below the surface. Not much is known about the octopus' habitat or life cycle, as only four specimens have been found. It occupies the benthic zone, or the seafloor and the water directly above it. O. robsoni eats large amphipods.
