Lesser Pacific Striped Octopus
The lesser Pacific striped octopus (Octopus chierchiae) lives in the Pacific waters of Central America and can be found by small rocks, shells, and cracks in the intertidal zone. Also known as the 鈥減ygmy zebra octopus,鈥 O. chierchiae is about the size of a table grape when full grown.聽Like terrestrial zebras, pygmy zebra octopus have unique stripe patterns. Each octopus can be individually identified by its markings throughout its life. Chierchiae hatchlings emerge from the egg bright orange and the size of a pen tip. They don鈥檛 develop dark contrasting stripes until they are a few weeks old.
Unlike other octopus species, which die as soon as they lay eggs, a female O. chierchiae lays several clutches of 30-90 eggs over her reproductive period.聽
Type: Cephalopod
Habitat: Rocky intertidal zone
Range: Pacific coast of Central America

Scientists at the 小蓝视频 and around the world study cephalopods to learn about everything from camouflage and limb dexterity to regeneration and neurobiology.
The 小蓝视频鈥檚 Cephalopod Mariculture team successfully bred O. chierchiae through multiple generations in 2019 鈥 a global first. Breeding multiple generations in the lab is known as 鈥渃losing the life cycle鈥 and it is critical in developing a genetic model for research. It lets scientists study gene function and mutational effects from one generation to the next. Females can lay up to 12 separate egg clutches over their reproductive life stage鈥攚ith new eggs laid every 30-90 days.
