Some English fisherman have hit the jackpot this season, hauling in tons of octopus, but the invasion of eight-legged molluscs also highlights the threat from marine heat waves. https://www.japantimes.co.jp/environment/2025/06/03/wildlife/octopus-english-channel-heat-wave/?utm_medium=Social&utm_source=mastodon #environment #wildlife #octopuses #heatwaves #uk #fishing

Blue-lined #octopus Hapalochlaena fasciata males envenomate females to facilitate copulation https://doi.org/10.1016/j.cub.2025.01.027

"Full-sized females are about the size of a golf ball – around two to five times bigger than their male counterparts... Sexual cannibalism is very common in #cephalopods... Males have developed distinct strategies to avoid falling prey to their mates during copulation."

Guide to Squid, Cuttlefish and Octopuses of Australasia by Mark Norman & Amanda Reid, 2020

The Australasian region is home to the greatest diversity of cephalopods — squid, cuttlefish, octopuses — in the world. Yet, we know very little about these fascinating marine animals. This book provides insights into the biology and behaviour of more than 60 species.

Punching #Octopuses Lead #Fish on Hunting Parties
Octopuses and fish are routinely seen working together on the #ocean floor,. When an #octopus found an interesting crevice in the #coral or rock, it would cover the crack with its body, trying to capture any prey inside. The octopus’s hunting was more efficient when it was traveling with fish partners: It checked out fewer crevices, but spent more time at each one, suggesting it was finding prey to slurp up

Happy World Octopus Day!

In the waters of the Red Sea, #fish and #octopuses are forming an unlikely alliance:
They’re joining forces to track down prey, establishing a hunting operation that’s potentially more effective than either creature working alone.

With the octopus leading the charge, fish scout for hidden prey and signal where to capture a smaller fish or mollusk.
But if freeloading fish are hovering around, looking to benefit from the hunt without contributing, the octopus punches them away, according to new research.

️“The octopus basically works as the decider of the group,” Eduardo Sampaio, a researcher at the Max Planck Institute of Animal Behavior and lead author of the study, tells Nature News’ Helena Kudiabor.
The study, published on Monday in Nature Ecology & Evolution, brought a new type of collective behavior to light. Octopuses, often thought of as solitary creatures, led a group of various species of fish and discerned which ones were and weren’t helping

#Octopuses and #fish share leadership—and enforcement—in group hunting https://www.npr.org/2024/09/23/nx-s1-5120912/octopuses-and-fish-hunt-enforce paper: https://www.nature.com/articles/s41559-024-02525-2

"The fish explore the environment. They find the prey. And then the #octopus chooses between the options that the fish give—and the octopus moves there, flushing out prey. Then the whole group moves with the octopus. So the fish present possible targets to the octopus, and the octopus selects the one it wants."

#Octopuses are extraordinary and inspiring

However #PescanovaCorp wants to cruelly cage these solitary creatures and intensively farm one million of them every year.

Confined to underwater tanks, these unique sentient #animals could become territorial & even cannibalistic.

What Can Cephalopods Teach Us About Adapting to Climate Change? https://www.mbl.edu/news/what-can-cephalopods-teach-us-about-adapting-climate-change

"One group that seems to be flourishing is the #cephalopods, a collection of marine organisms that include #octopuses, #cuttlefish, and #squid. Data show these three have actually seen an overall population increase in the last 60 years. Exactly why their numbers are going up is unknown, but their success means they could be a good model to study how organisms adjust to #ClimateChange."

Thousands of #Octopuses Gather at This Mysterious Spot. Now, We Know Why.
The "#OctopusGarden" is the location of the largest gathering of octopuses anywhere on Earth, and new research has an explanation. An estimated 20,000 Muusoctopus robustus octopuses, also known as pearl octopuses, occupy this 823-acre site where they find an oasis of warm water that accelerates the growth of #octopus embryos, providing a boost to their survival, reports a new study. https://www.vice.com/en/article/88xmdz/thousands-of-octopuses-gather-at-this-mysterious-spot-now-we-know-why

Why do thousands of deep-sea octopuses congregate two miles below the surface, at the base of an underwater mountain off California? Researchers now think they know the secret behind this real-life octopus garden, the largest known gathering of deep-sea octopuses on Earth....

"On the descent, the surface #ocean teems with gelatinous and soft-bodied #animals: #squid and #jellyfish undulating in and out of view. The #seafloor has a cast of characters: silvery rattail #fish trailing the vehicle, spider #crabs climbing into the basket, Dumbo #octopuses making appearances. And of course, the #worms, #mollusks, and #BacterialMats that thrive near vent systems."
