Abdopus abaculus, or the mosaic octopus, [1] is a species of pygmy octopus. [2] [3] It was first described as Octopus abaculus by M. D. Norman and M. J. Sweeney in 1997 based on specimens caught in Zamboanga del Norte, Philippines. [4]
A. abaculus have a mantle length of up to 33 millimetres (1.3 in) and a weight of up to 21 grams (0.74 oz). [5] They are dark gray to dark purple with cream to light purple spots. [6]
A. abaculus lays eggs of up to 2.4 millimetres (0.09 in). [7]
A. abaculus is found in the Philippines, [8] and has also been reported in Tonga [6] and Japan. [9] It is found at depths of zero to five metres (0 to 16 ft). [5]
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 center 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.
The Octopodidae comprise the family containing the majority of known octopus species.

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.
Amphioctopus marginatus, also known as the coconut octopus and veined octopus, is a medium-sized cephalopod belonging to the genus Amphioctopus. It is found in tropical waters of the western Pacific Ocean. It commonly preys upon shrimp, crabs, and clams, and displays unusual behavior including bipedal and quadrupedal walking as well as tool use.
Abdopus is a genus of octopuses in the family Octopodidae.
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.
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 and arms 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.
Sepioloidea lineolata or more commonly known as the striped pyjama squid or the striped dumpling squid is a type of bottletail squid that inhabits the Indo-Pacific Oceans of Australia. Although traditionally falling within Sepiida, the cuttlefish order, it lacks a cuttlebone. More recent phylogenomic evidence suggests bottletail and bobtail squid may form their own order, Sepiolida. The striped pyjama squid lives on the seafloor and is both venomous and poisonous. When fully mature, a striped pyjama squid will only be about 7 to 8 centimetres in length. Baby striped pyjama squid can be smaller than 10 millimetres (0.39 in).
Wunderpus photogenicus, the wunderpus octopus, is a small-bodied species of octopus with distinct white and rusty brown coloration. 'Wunderpus' from German “wunder” meaning ‘marvel or wonder’.
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 insularis is a species of octopus described in 2008 from individuals found off the coast of Brazil, with a potentially much larger range.
Abdopus undulatus is a species of octopus within the family Octopodidae. The species is found near the coasts of Tongatapu, Tonga, in benthic environments at depths of 8 to 20 metres. Individuals to grow up to 3.3 centimetres (1.3 in) in length.
Octopus conispadiceus is a species of long-ligula octopus, provisionally placed in the genus Octopus. It was first described by Madoka Sasaki in 1917 based on specimens bought at a fish market in Sapporo, Japan.
Octopus superciliosus is a species of octopus. It was first described in 1832 by Jean René Constant Quoy and Joseph Paul Gaimard based on a specimen found off Victoria during the 1826 to 1829 voyage of the Astrolabe.
Octopus vitiensis, or the bighead octopus, is a species of octopus provisionally placed in the genus Octopus. It was described by William Evans Hoyle in 1885 based on a specimen found in reefs in Kandavu, Fiji during a voyage of HMS Challenger.
Callistoctopus rapanui, or the rapanui octopus, is the only endemic octopus species in Rapa Nui. It was first described by Gilbert L. Voss in 1979 as Octopus rapanui.
