An octopus (pl.: octopuses or octopodes [a]) is a soft-bodied, eight-limbed mollusc of the order Octopoda (/ ɒ k ˈ t ɒ p ə d ə /, ok-TOP-ə-də [3]). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.
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).

The Atlantic pygmy octopus (Octopus joubini), also known as the small-egg Caribbean pygmy octopus, is a small species of octopus in the order Octopoda.Fully grown, this cephalopod reaches a mantle length of 4.5 cm (1.8 inches) with arms up to 9 cm (3.5 inches) long. [2]

Furthermore, the cirrate octopuses lack innervated chromatophores and therefore are not capable of changing color [14] (despite some unreferenced statements to the contrary). [35] How cirrate octopuses escape or avoid predators is largely unknown.

Many prey animals, and to defend against seed predation also seeds of plants, [55] make use of poisonous chemicals for self-defence.
