Pinnoctopus
''Pinnoctopus'' is a genus of octopuses in the family Octopodidae. It is of doubtful validity. Species * ''Pinnoctopus cordiformis'' ( Quoy and Gaimard, 1832. ''nomen dubium'' * ''Pinnoctopus kermadecensis'' (Berry, 1914) Taxonomic note ITIS treats ''Pinnoctopus'' as a synonym of ''Octopus'' Cuvier, 1797. While the World Register of Marine Species treats it as a nomen dubium In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a s ..., has ''P. cordiformis'' as a species of doubtful validity and assigns ''P. kermadecensis'' to ''Octopus''.

Paroctopus
''Paroctopus'' is a small genus of octopuses from the family Octopodidae. ''Paroctopus'' are small-bodied; short mantled, pouch like octopuses with short, stocky arms which are 2 or 3 times the length of the mantle. The males have 1-3 enlarged suckers on each arm with their right third arm being hectocotylised and shorter than its opposite arm. There are stylets and these are non-mineralised. One to 3 enlarged suckers on all arms of males only. The ligula is of medium size with a short calamus. Their gills have 6‑8 lamellae per outer demibranch. ''Paroctopus'' lays small to medium-sized eggs which are on very short stalks and are attached singly in small clusters within the empty shells of gastropods and bivalves. They are uniformly coloured with little variation in pattern and they lack a patch and groove system. There is a faint frontal white spot complex. The integument lacks large primary papillae. The species of Paroctopus are distributed in the northeastern Pacific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callistoctopus
''Callistoctopus'' is a genus of nocturnal, orange octopuses in the family Octopodidae.Marshall, B.; Bouchet, P. (2014). Callistoctopus Iw. Taki, 1964. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=534103 on 2015-02-02 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'' (Atlantic white-spotted octopus) and the type species '' C. ornatus'' (ornate octopus), both of which are harvested for human consumption as seafood.

Macrochlaena
''Macrochlaena winckworthi'', Winckworth's octopus, is a little known species of octopus, it is the only species in the monotypic genus ''Macrochlaena'', in the family Octopodidae. It was described by the British malacologist Guy Coburn Robson in 1926, the type specimens having been collected in the Gulf of Mannar, off Thoothukudi in Tamil Nadu, southeastern India. Description ''Macrochlaena winckworthi'' is a small species of octopus with relatively short arms, the arms being 1.5-2.5 times longer than the mantle with the lateral arms being slightly longer. The web is relatively deep, being one third the length of the arms, and the web is slightly deeper between the lateral arms. There are no pouches between the arms. Each arm has two rows of small suckers n its underside, with each arm having around 65 suckers. The funnel organ has a shape described as "UU" and the gills have 8 to 10 lamellae per demibranch. The radula has 9 elements, 7 teeth rows and marginal plates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Blue-ringed Octopus
The greater blue-ringed octopus (''Hapalochlaena lunulata'') is one of four species of highly venomous blue-ringed octopuses belonging to the family Octopodidae. This particular species of blue-ringed octopus is known as one of the most toxic marine animals in the world. Physical characteristics The greater blue-ringed octopus, despite its vernacular name, is a small octopus whose size does not exceed 10 centimeters, arms included, for an average weight of 80 grams. Its common name comes from the relatively large size of its blue rings (7 to 8 millimeters in diameter), which are larger than those of other members of the genus and help to distinguish this type of octopus. The head is slightly flattened dorsoventrally (front to back) and finished in a tip. Its eight arms are relatively short. There are variable ring patterns on the mantle of ''Hapalochlaena lunulata'' with varied coloration in correlation to their ambient environment, from yellow ocher to light brown or even whi ...

Lepidoctopus
''Lepidoctopus joaquini'' is a little-known species of small octopus in the family Octopodidae. It is the only known species in the monotypic genus ''Lepidoctopus'', and is endemic to the Amazon Reef system of the Atlantic Ocean, where it lives in benthic habitats. It was discovered during surveys that attempted to map the cephalopod diversity of the reef system by analyzing the stomach contents of southern red snappers (''Lutjanus purpureus''), and is currently only known from specimens found in such stomach contents. Genetic analysis of the specimens has found ''Lepidoctopus'' to be a basal member of the Octopodidae that represents a clade A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

Wunderpus
''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’. Due to the appearance and behavior of the wunderpus, it is frequently confused with its close relative, the mimic octopus. The wunderpus octopus was not discovered until the 1980s and was only officially described in detail in 2006. The wunderpus octopus is important commercially to the underwater photography, dive and tourism communities, especially throughout Indonesia. The wunderpus is also valued as an expensive ornamental marine species for the home aquarium. Appearance An adult wunderpus octopus displays an individually unique pattern of white spots and bands over a rusty brown background. Even though each body pattern is unique to the individual, generally all wunderpus octopuses display a circular pattern of about six white spots at the posterior lip of its mantle, h ...

Thaumoctopus
The mimic octopus (''Thaumoctopus mimicus'') 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.Maculay, G. (January 6, 2012)"Mimic Octopus Creature Feature - Diving with Mimics" Dive The World - Scuba Diving Vacations - Dive Travel - Diving Holidays - Liveaboards. Retrieved April 21, 2013. 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.Harmon, K. (February 21, 2013)"Mimic Octopus Makes Home on Great Barrier Reef" ''Scientific American''. Retrieved April 21, 2013. Appearance The mimic octopus is a smaller octopus, growing to a total length of about , including arms, with a diameter approximately that of a penci ...
