Opisthoteuthidae are a group of octopuses characterized by a web of skin in between their arms. They broad U-shaped shell that support muscles for a pair of small fins on the mantle, these fins are far less developed than other families in Cirrina and essentially only act as stabilizers when the animal swims (using a medusoid motion of the arms and webbing). [1]
The longitudinal muscles run parallel to the length of the octopus and they are used in order to keep the mantle the same length throughout the jetting process. Given that they are muscles, it can be noted that this means the octopus must actively flex the longitudinal muscles during jetting in order to keep the mantle at a constant length.
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 ...
In argonauts, the male transfers the spermatophores to the female by putting its hectocotylus into a cavity in the mantle of the female, called the pallial cavity. This is the only contact the male and female have with each other during copulation, and it can be at a distance. During copulation, the hectocotylus breaks off from the male.
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. There are 17 species recognized in the genus. [3] [4]

East Pacific red octopus, rescued from a gull near Los Osos, California.

The mantle, including the beak and mouth, is located at the center of eight arms. Each of the arms is lined with suckers that are used to help with grasping prey, rocks, and forming shelters. Similar to other octopus species, O. bimaculatus has skin covered in chromatophores . [ 2 ]
