Octopus chierchiae is commonly known as the lesser Pacific striped octopus or pygmy zebra octopus.[1][2] It has been proposed as a

iteroparity), compared to most octopus species that are semelparous and die after one reproductive event.[3][4]
This makes Octopus chierchiae a candidate for sustainable and multigenerational laboratory research.

Description

Octopus chierchiae is a small octopus found in the central Pacific coast of the Americas, most often in Central America but sightings have been reported as far north as the

Octopus vulgaris
) can be three to ten times larger. They can be identified by individualized striped patterns on the dorsal mantle surface that are unique to each organism and are present throughout their lifetime. These stripes may be visible with magnification as soon as five days after hatching. This allows for non-invasive identification that might increase stress in a laboratory setting.

Males and females are both sexually and behaviorally

suckers on the tip of their third right arm and instead have a hectocotylus, a sex organ that passes spermatophores
to the female during mating. Octopus chierchiae reach sexual maturity around 6 months of age and can lay multiple clutches of eggs, approximately every 30 to 90 days.

Octopus chierchiae is closely related to the Larger Pacific striped octopus (LPSO), the only known social species of octopus that exhibits beak-to-beak mating and den-sharing among mated pairs. Octopus chierchiae is not known to exhibit any of these behaviors. However the egg development progression of Octopus chierchiae is similar to that of the LPSO.[5]
