Roy Caldwell, a behavioral ecologist on the College of California, Berkeley, first met Octopus chierchiae, additionally known as the lesser Pacific striped octopus, within the mid-Seventies in Panama. He was pulling rocks from the ocean to search out mantis shrimp hiding in cracks. “Each infrequently, these cute little striped octopus would come out,” he mentioned.
He introduced just a few of the octopuses again to Berkeley. Quickly after, “One of many females laid eggs, and I assumed that was form of a bummer as a result of I knew that she would die,” Dr. Caldwell mentioned. “And she or he didn’t die.” A few months later, she laid eggs once more.
A 1984 paper by Arcadio Rodaniche, a Panamanian scientist, confirmed Dr. Caldwell’s statement: Females of this species, in contrast to practically each different octopus, might reproduce a number of occasions.
This trait, mixed with their handy measurement, made them an attractive topic for lab analysis. Sadly, Dr. Caldwell couldn’t discover any extra in Panama. Not one of the biologists or collectors he requested had seen any, both.
The little cephalopod was solely a reminiscence till round 2010, when “I received an e mail from a highschool pupil,” Dr. Caldwell mentioned, “who wished to understand how he might handle his new pet octopus.” The scholar despatched a photograph. The octopus’s zebra stripes have been unmistakable.
Dr. Caldwell traced the octopus again to a collector in Nicaragua. Lastly, he might get hold of just a few lesser Pacific striped octopuses and attempt to get a colony getting into his lab. However over three or 4 years of makes an attempt, he by no means received previous the second technology. After that, Dr. Caldwell mentioned, the females’ eggs didn’t hatch. He suspected inbreeding was an issue, in addition to food plan. “We didn’t know fairly what to feed them.”
That query was nonetheless unanswered in 2016, when Dr. Rosenthal got here to the Marine Organic Laboratory with a dream of constructing mannequin cephalopods to help scientific analysis. He recruited Mr. Grasse, who was often known as one thing of a cephalopod whisperer, from the Monterey Bay Aquarium in California. Taylor Sakmar, additionally a Monterey Bay aquarist, got here to Cape Cod to assist construct a brand new form of facility for many-armed animals.
