The Octopus Overlooked By Science | Squid With ‘Giant’ Eggs Could Be New Species

The larger Pacific striped octopus is unusually social. But it wasn’t recognized by scientists until 2015, despite one man’s efforts. And, a deep-sea squid in the family Gonatidae was filmed cradling large eggs for its body size, which suggests it’s an entirely new species.

Why It Took Decades For This Octopus To Be Recognized

Octopus mating behaviors can be quite deadly. Many species are cannibalistic, making the entire prospect of mating dangerous, and female octopuses often die after laying one clutch of eggs. Their cannibalistic tendencies mean that octopuses don’t socialize as much as other animals.

But the larger Pacific striped octopus (LPSO) is different. For one, they live together in colonies. And mating is not only a safer proposition, it involves beak-to-beak “kissing.” Plus, females can lay eggs repeatedly, even tending to embryos at various stages of development.

But because these behaviors are so uncharacteristic of most octopuses, the scientific community didn’t officially recognize their existence until 2015, despite the decades-long effort of a Panamanian diver and artist named Arcadio Rodaniche. When he tried to share his findings about the LPSO at a symposium and publish them in a journal, he was flatly rejected. But his persistent research and documentation of the species would eventually be validated when researchers were able to obtain and observe the octopuses in captivity.

SciFri producer Kathleen Davis sits down with freelance science writer Kenna Hughes-Castleberry to talk about an article she reported for Science Friday about the late Rodaniche and his yearslong effort to get official scientific recognition for the LPSO.

Squid With ‘Giant’ Eggs Could Be A New Species

To finish up our celebration of Cephalopod Week we wanted to share a bit of squid news. A group of researchers recently identified a potentially new squid species in the family Gonatidae. Scientists took a closer look at some video footage captured back in 2015 and found a deep-water squid that was cradling some rather large eggs, which was not in line with other squid of the same family.

John Dankosky talks with Dr. Bruce Robison, midwater ecologist and senior scientist at the Monterey Bay Aquarium Research Institute, about this new discovery.
