A complex hydraulic mechanism releases the sperm from the spermatophore, and it is stored internally by the female. [26] Female giant Pacific octopus guarding strings of eggs. 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 ...
The optic gland in female octopuses is associated with their maternal behavior of guarding their eggs without feeding. [2] This self-starvation results in the death of the female octopus before her eggs have hatched. [3] In captivity, some starving females also self-mutilate and entangle their arms in an apparent effort to die even faster.
Georges Cuvier's original illustration of an octopus hectocotylus, which he named Hectocotyle octopodis. A hectocotylus (pl.: hectocotyli) is one of the arms of male cephalopods that is specialized to store and transfer spermatophores to the female. [1] Structurally, hectocotyli are muscular hydrostats.
This part of the male arm anatomy contains no suckers. Large spermatophores are characteristic of octopuses in this genus. [40] The female stores the spermatophore in her spermatheca until she is ready to fertilize her eggs. One female at the Seattle Aquarium was observed to retain a spermatophore for seven months before laying fertilized eggs ...
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 ...
Cephalopod limbs bear numerous suckers along their ventral surface as in octopus, squid and cuttlefish arms and in clusters at the ends of the tentacles (if present), as in squid and cuttlefish. [9] Each sucker is usually circular and bowl-like and has two distinct parts: an outer shallow cavity called an infundibulum and a central hollow ...
Recently, scientists have witnessed a species of octopus, the gloomy octopus (Octopus tetricus), engaging in even more extraordinary acts than previously Find Out Why These Octopuses Throw Things ...
Female cephalopods lay eggs in clutches; each egg is composed of a protective coat to ensure the safety of the developing embryo when released into the water column. Reproductive strategies differ between cephalopod species. In the giant Pacific octopus, large eggs are laid in a den; it will often take several days to lay all of them. [112]
