The male almost certainly dies shortly after mating. [3] There is competition between the males; multiple male arms have been found in the mantle cavity of females. [3] The females carry more than 100,000 eggs attached to a sausage-shaped calcareous secretion held at the base of the dorsal arms and carried by the female until hatching. [5]
In male seven-arm octopuses (Haliphron atlanticus), the hectocotylus develops in an inconspicuous sac in front of the right eye that gives the male the appearance of having only seven arms. 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 ...
The common blanket octopus or violet blanket octopus (Tremoctopus violaceus) [4] is a large octopus of the family Tremoctopodidae found worldwide in the epipelagic zone of warm seas. The degree of sexual dimorphism in this species is very high, with females growing up to two meters in length, whereas males grow to about 2.4 cm.
In some instances, a female octopus would launch materials at a nearby male who was trying to mate with her. Perhaps it’s her way of communicating that she wasn’t interested in his attention.

About forty days after mating, the female giant Pacific octopus attaches strings of small fertilised eggs (10,000 to 70,000 in total) to rocks in a crevice or under an ...
When the University of Georgia’s Marine Education Center and Aquarium acquired a common octopus recently, they got somewhat more than they bargained for. A 'male' octopus surprised its keepers ...
During reproduction, the male octopus deposits a spermatophore (or sperm packet) more than 1 m (3.3 ft) long using his hectocotylus (specialized arm) in the female's mantle. The hectocotylus is found on the third arm of male octopuses and occupies the last four inches of the arm. [ 39 ]
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.
