In a new paper published in the journal Frontiers in Marine Science, researchers from the Marine Biology Laboratory (MBL) introduced scientists to the successful cultivation method of O.
chierchiae developed at MBL
"Compared with other octopuses, the Pacific striped octopus ( Octopus chierchiae ) has certain biological characteristics that make them more attractive and more suitable for laboratory research," said Bret Grasse, who wrote this article.

O.
chierchiae has many useful similarities with other research organisms—such as adult small size—but it also has some unique characteristics that compare it with other cephalopods (a group of animals including octopus, squid, and cuttlefish) Differentiate
.
"Most octopuses are'live fast and die early
.
' They reproduce only once, then immediately begin to age and age, and then die relatively quickly," said Anik Grearson, a former MBL intern and co-first author of the paper.
"We can let them mate and know exactly when they lay their eggs
.
We know exactly how long they will hatch, and we can raise offspring with a relatively high survival rate compared to other octopuses," Grasse said
MBL's cephalopod mariculture team successfully cultivated multiple generations of O.
chierchiae in 2019, the first in the world
.
Multi-generation reproduction in the laboratory is called "closed life cycle", which is crucial in biological research
Glass said that being able to successfully reproduce O.
chierchiae in the laboratory opened up "a new science that was impossible before
.
"
MBL and scientists around the world study cephalopods to understand everything from camouflage and physical dexterity to regeneration and neurobiology
.
Most American scientists who study octopuses use California double-spotted octopus ( O.
Octopuses also have territorial awareness, and every creature must live alone
.
An adult double-spotted octopus is about the size of a softball, while an adult O.
Grasse said: "We now have this octopus species.
It is really small and can be reproduced regularly
.
