Lesser Pacific Striped Octopus

Octopus chierchiae, commonly known as the lesser Pacific striped octopus or pygmy zebra octopus, is a small marine cephalopod belonging to the Octopodidae family and the Octopus genus. O. chierchiae is native to the eastern tropical Pacific, specifically along the coasts of Panama and Costa Rica, where it inhabits shallow benthic environments including rubble, rocky crevices, and sandy substrates from the intertidal zone to depths of about 100 m. O. chierchiae is characterized by its distinctive dark-and-light banding patterns, which are individually unique and remain fixed throughout its lifespan. O. chierchiae, unlike most octopus species, which are semelparous, is iteroparous. These characteristics have led to its emergence as a model organism in laboratory research. Although increasingly studied in captivity, the species' wild population is poorly understood and is currently listed by the International Union for Conservation of Nature (IUCN) as Data Deficient.
