Abdopus is a genus of octopuses in the family Octopodidae. [1]
The Octopodidae comprise the family containing the majority of known octopus species.
The mimic octopus is a species of octopus from the Indo-Pacific region. Like other octopuses, it uses its chromatophores to disguise itself with its background. However, it is noteworthy for being able to impersonate a wide variety of other marine animals. Although many animals mimic either their environment or other animals to avoid predation, the mimic octopus and its close relative the wunderpus are the only ones known to actively imitate a number of animals in order to elude predators.
Octopus is the largest genus of octopuses, comprising more than 100 species. These species are widespread throughout the world's oceans. Many species formerly placed in the genus Octopus are now assigned to other genera within the family. The octopus has 8 arms, averaging 20 cm long for an adult.
Adelieledone is a genus of octopuses in the family Megaleledonidae.
Pinnoctopus is a genus of octopuses in the family Octopodidae. It is of doubtful validity.
Robsonella is a small genus of octopuses in the family Octopodidae. It contains two described species. Robsonella octopuses can be found on the central-south coast of Chile. If an octopus’ first lateral tooth in the radula is crescent shaped; this allows you to identify it as a Robsonella fontaniana. One species in the genus, Robsonella fontaniana, inhabit the coastal waters of Chile and range from northern Peru to Golfo Nuevo in Argentina. Robsonella fontaniana are very small, have rugged skin and each eye has a fleshy expansion.
Scaeurgus is a genus of octopuses in the family Octopodidae. The species of this genus are characterized by inhabiting the upper bathyal benthic zone from temperate and tropical latitudes in all major oceans.
Enteroctopus megalocyathus, also known as Patagonian red octopus (EN), Pulpo del sur (Chile) and Pulpo colorado (Argentina); is a medium-sized octopus, and the type species for the genus Enteroctopus.
Amphioctopus is a genus of octopuses comprising around 16 species.
Amphioctopus fangsiao, called webfoot octopus, is a species of octopus, a cephalopod belonging to the genus Amphioctopus. It is found in the Pacific Ocean, including off the coasts of New Zealand as well as in the Yellow Sea and surrounding Chinese shores. It is also commercially fished.
Abdopus aculeatus is a small octopus species in the order Octopoda. A. aculeatus has the common name of algae octopus due to its typical resting camouflage, which resembles a gastropod shell overgrown with algae. It is small in size with a mantle around the size of a small orange (≈7 cm) and legs 25 cm in length, and is adept at mimicking its surroundings.
Macrotritopus defilippi, commonly known as the Lilliput longarm octopus or the Atlantic longarm octopus, is a small species of octopus, a marine cephalopod mollusc of the order Octopoda.
Callistoctopus is a genus of nocturnal, orange octopuses in the family Octopodidae. They are readily identifiable by their reddish coloring, the white papillae that line their bodies, and their long arms. Though sympatric with diurnal Octopus species, they avoid competition by hunting at night. In acknowledgement of this preference, many species of Callistoctopus are referred to as night octopuses. Well-known species include C. macropus and the type species C. ornatus, both of which are harvested for human consumption as seafood.
Microeledone mangoldi, the sickle-tooth pygmy octopus, is a species of octopus from the family Megaleledonidae. This species was described in 2004, the type specimen being a male which was collected from a depth of approximately 1,000 m (3,300 ft) near the Norfolk Ridge, in the southwest Pacific Ocean near New Caledonia. It is a very small octopus which has a single row of suckers, lacks an ink sac and has a radula with seven rows of teeth with the unique central tooth, called the rechidian tooth, being curved with a grooved tip. The remaining teeth are flat and plate like and so are also distinctive. The smooth creamy-pink body lacks any chromatophores. The specific name honours the Swiss malacologist and marine biologist Katharina Mangold-Wirz (1922-2003).
Cistopus is a genus of octopuses in the family Octopodidae from the Indo-Pacific region, colloquially known as old-lady octopuses. For a long time it was thought that Cistopus was monotypic with the type species, C. indicus, being the only known species. This species was characterised by the possession of eight small mucus filled pouches around the animal's mouth in the web between the bases of each arm, these have an opening which releases the mucus. The function of these pouches is unknown. A new species, C. taiwanicus was described in 2009 from Taiwan. Octopuses in the genus Cistopus are harvested and utilised for food on a commercial basis in southern and eastern Asia. Further new species have been described since then.
Galeoctopus lateralis, the sharkclub octopus, is a species of octopus, from the family Octopodidae. This species was described in 2004 from specimens collected at depths of 200–400 m in the southern and western Pacific Ocean. It is a small octopus in which the mature male's have a distinctive ligula which superficially resembles a shark's jaw and head including teeth‐like lugs. Other distinguishing characteristics include a lateral mantle ridge, a skin sculpture which includes star-shaped papillae, and the females have oviducts with hare distally swollen.
Octopus oliveri, is a species of octopus found in the western Pacific Ocean off the coast of Japan, Hawaii, and Kermadec Island, in reefs and boulder coasts.
Octopus pallidus, the pale octopus, is a species of octopus found in the Southwest Pacific.
Octopus insularis is a species of octopus described in 2008 from individuals found off the coast of Brazil, with a potentially much larger range.
Abdopus capricornicus is a species of octopus in the family Octopodidae, native to the Great Barrier Reef. Individuals are capable of autotomy, sacrificing a writhing arm to a predator to distract it while making an escape.
