WASHINGTON (AP) — Most octopuses lead solitary lives. So scientists were startled to find thousands of octopus huddled together, protecting their eggs at the bottom of the ocean off the central California coast.
Now researchers may have solved the mystery of why these pearl octopus congregate: Heat seeping up from the base of an extinct underwater volcano helps their eggs hatch faster.

“There are clear advantages of basically sitting in this natural hot tub,” said Janet Voight, an octopus biologist at the Field Museum of Natural History in Chicago and co-author of the study, which was published Wednesday in Science Advances.
The researchers calculated that the heated nest location more than halved the time it took for eggs laid there to hatch — reducing the risk of being munched by snails, shrimp and other predators....

The Octopus in my House

Interesting programme about a Canadian professor who brings an octopus into a large tank in his living room to study close up & learn about it’s intelligence.. He & his daughter form some sort of relationship with it.

The octopus, called Heidi, can recognise individual humans & appears to watch tv with the family. In one section Heidi changes colour & skin texture while it seems to be asleep. The assumption is it’s dreaming.
 

Family who got their nine-year-old son a pet octopus reveal how it upended their life and destroyed their home after giving birth to 50 babies


An Oklahoma family had no idea that a birthday gift for their nine-year-old son would lead to the birth of 50 octopus babies, numerous water tanks that took over half of a bathroom, and thousands of dollars on food supplies and water damage repairs.

Cameron Clifford, a 36-year-old dentist, said his son Cal had been obsessed with octopuses since the age of three.

'Every birthday, every Christmas, every holiday, he would always say: 'All I want is an octopus,'' Clifford [said].

In October, Clifford made a call to a local aquarium store and acquired a female California two-spot octopus for Cal's ninth birthday. They named her Terrance.

Clifford ordered a saltwater tank, a water cycling system and food supplies for Terrence, mostly from Facebook marketplace. He thought it would cost around $600.

Terrance the octopus ended up hatching a total of 50 babies, and 'all bets went off,' he said.

The family had to arrange 50 separated homes for the unexpected offspring, spend thousands of dollars on clams, crabs, and snails, not to mention the costs to repair the damage to the house from spilled water and a small electrical fire.

Terrence is still alive, Clifford said.

'She's doing good. She is just living out the rest of her life in her tank by herself. She will probably die in the next several weeks, although my assumptions of her have been wrong consistently.'

The family has become famous too, as Clifford has amassed nearly 400 thousand followers on TikTok.
