Luteuthis shuishi is a species of octopus that lives in the South China Sea, which is known only from one female specimen collected at a depth of 767 meters. It has short arms and is quite gelatinous. [3] The octopus's total length is about 300 millimeters. [4]
An octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda. The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the centre point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates.
Luteuthis dentatus, also known as Lu's jellyhead, is a medium-sized species of cirrate octopus found in the southwestern Pacific, originally described by Steve O'Shea.
Ocythoe tuberculata, also known as the tuberculate pelagic octopus or football octopus, is a pelagic octopus. It is the only known species in the family Ocythoidae.
Octopus cyanea, also known as the big blue octopus or day octopus, is an octopus in the family Octopodidae. It occurs in both the Pacific and Indian Oceans, from Hawaii to the eastern coast of Africa. O. cyanea grows to 16 cm in mantle length with arms to at least 80 cm. This octopus was described initially by the British zoologist John Edward Gray in 1849; the type specimen was collected off Australia and is at the Natural History Museum in London.
Steve O'Shea is a marine biologist and environmentalist known for his research on giant squid.
Callistoctopus macropus, also known as the Atlantic white-spotted octopus, white-spotted octopus, grass octopus or grass scuttle, is a species of octopus found in shallow areas of the Mediterranean Sea, the warmer parts of the eastern and western Atlantic Ocean, the Caribbean Sea, and the Indo-Pacific region. This octopus feeds on small organisms which lurk among the branches of corals.
The seven-arm octopus, also known as the blob octopus or sometimes called septopus, is one of the two largest known species of octopus; the largest specimen ever discovered had an estimated total length of 3.5 m (11 ft) and mass of 75 kg (165 lb). The only other similarly large extant species is the giant Pacific octopus, Enteroctopus dofleini.
Opisthoteuthis japonica is a species of octopus that lives in the Pacific Ocean near Japan. Its mantle is about 45 millimeters long, and it's been found at 152 meters deep. O. japonica lives in the neritic zone.
Grimpoteuthis boylei is a species of octopus known from only ten individuals.
Grimpoteuthis challengeri is a species of large octopus living in the abyssal zone.
Grimpoteuthis hippocrepium is a species of octopus. It is only known from one specimen found in 1904, which was poorly preserved. Some characteristics G. hippocrepium are unknown.
Grimpoteuthis megaptera is a species of octopus known from five specimens, collected by Addison Emery Verrill. Between two and three of these specimens may belong to different species.
Grimpoteuthis pacifica is an octopus known from one badly damaged specimen. It is not completely described, and it is not easily separated from some other species of octopus. Nothing clearly differentiates G. pacifica from Grimpoteuthis hippocrepium except for its type locality.
Grimpoteuthis tuftsi is an octopus known from seven specimens.
Grimpoteuthis wuelkeri is a medium-sized octopus characterized from multiple specimens.
Opisthoteuthis albatrossi is a cirrate octopus originally found off Kinkasan in Japan. This species was described from only four specimens. It is similar to Opisthoteuthis californiana; the two may be the same species. It is also similar to Opisthoteuthis japonica.
Opisthoteuthis bruuni is a species of finned cirrate octopus found along the western coast of South America. Their tissue is almost jelly-like, and they have short, round bodies.
Opisthoteuthis depressa, also known as the Japanese flapjack octopus, is an octopus found in waters near Japan.
Opisthoteuthis medusoides is a cirrate octopus living off the coast of Tanzania near Dar es Salaam. However, its actual range may be more extensive.
Grimpoteuthidae are a family of bentho-pelagic octopuses, comprising three currently accepted genera. They have extensive arm webbing and relatively large fins allowing for powerful fin swimming.
