This octopus' mantle reaches 53 millimeters long, and it weighs at least 1,345 grams when wet. [4] Every arm has between 60 and 70 suckers, which are small. Like other cirrates, G. meangensis has a web covering its arms to some degree; the web of G. meangensis covers the majority of its arms. The cirri on these arms are short. [3]
Macrotritopus defilippi is a small octopus with relatively long arms and a mantle length of up to 90 mm (3.5 in). As is the case in most octopuses, the skin is variable in colour. It is usually either plain or speckled and closely matches the colour of its surroundings, the sandy plains on which it lives.
This octopus' mantle reaches 43 millimeters long, and a total length up to 156 millimeters long on the type material, it has an internal shell shaped like the letter "U". [6] [4] Some additional specimens captured since its description are somewhat larger, with a mantle length up to 77 millimeters. [5]
Grimpoteuthis [1] is a genus of pelagic cirrate (finned) octopods known as the dumbo octopuses. [2] 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.
Opisthoteuthis agassizzi octopuses are small compared to most octopuses; males weigh up to four times more than females, and have a mantle length from 1 up to 2 + 1 ⁄ 2 inches. Males suckers are also much larger. The largest specimen, a male, had a mantle (the body not including the octopus' arms) reaching 63 mm, a little under two and a half ...
Like other cirrate octopods, G. challengeri has fins on either side of its mantle that it uses to swim through the ocean. This octopus's fins are long. It also has a beak, as do other octopuses. [5] G. challengeri is a red-brown color when preserved, and its fins have a slight purple hue. [5] The octopus's lifespan is unknown.
It has the common name 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 ( c. 7 cm or 3 inches) and arms 25 cm (10 inches) in length, and is adept at mimicking its surroundings.
