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.
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.

Eggs are fertilized upon exiting the oviducts. Female octopuses generally lay their eggs in shallow water and stays with the egg mass in order to protect it. [14] In the species A. aculeatus which is closely related to A. capricornicus, female octopuses rarely reject the mating advances of the male octopus. It was also seen that males of this ...
Vitreledonella richardi, also known as the glass octopus, is a transparent, gelatinous, and almost colorless meso-to bathypelagic octopod found worldwide in tropical and subtropical seas. Because this octopus mostly lives in deep ocean waters, there have been very few observations of it in the wild.
The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell (hence the name paper nautilus). The shell is usually approximately 150 mm in length, although it can exceed 200 mm in exceptional specimens; the world record size is 220.0 mm. [ 1 ]
A female argonaut is also described in Marianne Moore's poem "The Paper Nautilus". "Argonauta" is the name of a chapter in Anne Morrow Lindbergh's Gift from the Sea . Paper nautiluses were caught in The Swiss Family Robinson novel.
This also makes it the longest-living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone. [ 4 ] [ 5 ] Female Graneledone boreopacifica tend to brood their eggs between the depths of 1,200 and 2,000 metres (3,900 and 6,600 ft); the eggs were never unattended.
