Crabs can’t hide from an #octopus with a mirror
Wild-caught #cephalopods can learn to hunt for crabs using only their prey’s reflection
Initially, the octopuses approached the mirror, then turned around to find their prey. But after about 10 to 12 trials, each animal learned to crawl directly to the crab without the mirror pit stop.

phew, glad to hear that #octopus farming plan has fallen through. To me that was about as defensible as eating dogs. https://www.theguardian.com/environment/2026/aug/13/environment-food-farming-intelligence-eating-octopus-ethics-sustainability

I wrote about the project in my feature Octopus etiquette in 2023: https://proseandpassion.blogspot.com/2023/10/all-about-cephalopods.html

An evaluation of over 300 scientific studies found «very strong evidence for sentience» in #cephalopods. The authors concluded that welfare-compliant commercial #octopus farming under the planned intensive conditions was fundamentally impossible. Further studies showed that octopuses avoid places where they had experienced pain and prefer places where they had been given painkillers, a clear indication of consciousness and the capacity for memory

Ocean acidification may be shrinking the brains of the world's most intelligent invertebrates https://phys.org/news/2026-07-ocean-acidification-brains-world-intelligent.html 🦑 #ClimateChange #ClimateCrisis #MarineBiology #MarineLife #Science #Squid #Cephalopods

Larger brains are frequently found in social species, leading to the supposition that sociality is a driver of brain size. Based on evaluation of cephalopods, a new paper argues that environmental complexity, not social factors, are responsible for brain size in these organisms.

100% agree. #GenAISlop machines are designed for #outsourcing brain functions. Not only are we guaranteed of becoming ever more stupid, but we’ll pay for the privilege. we could learn a thing or two from #cephalopods .

Giant, #kraken-like #octopuses may have ruled the #Cretaceous deep
Fossilized jaws reveal that enormous octopuses growing up to 19 meters long were top predators in the #oceans during an era when #dinosaurs ruled on land. These super-sized #cephalopods would have been the largest marine animals of the Cretaceous Period and may be the biggest #invertebrates to ever live

• Biological Algorithms: Examines innate, pre-programmed instincts—such as the path integration of desert ants or the inherited migration maps of bar-tailed godwits—functioning with the complexity of modern aircraft navigation software.

• Cognitive Flexibility: Explores how animals like #cephalopods use associative learning and problem-solving to navigate unpredictable environments where rigid programming fails.

What If Cephalopods Are the Closest Thing to Alien Intelligence?

What if the most profound encounter with a truly alien intelligence isn’t light-years away, but lurking beneath the waves of our oceans and seas?

From @joannechocolat

Jeanne Villepreux-Power (1794 – 1871), was a pioneering #French marine biologist, described by English biologist Richard Owen as the "Mother of Aquariophily."

In 1832 she was the first person to invent and create aquaria for experimenting with aquatic organisms.

Personal note: She created the first offshore research stations — a system of immense cages she anchored off the coast of #Sicily, complete with observation windows through which she could study #argonauts * undisturbed. 🐙

(* an octopus known as paper #nautilus for the thin, intricately corrugated shell of its females and the sail-like membranes protruding from it like a pair of bunny ears)

Every day, she prepared food for them, rowed her boat to the cages in her long skirts (👀 !!), and knelt at the platform, observing for hours on end.

As one can imagine, that got old fast (!!) so, in order to transfer her observations and experiments ashore, she pioneered the #aquarium.

🦑🇦🇺 The giant Australian #cuttlefish is the largest species of its kind and gathers annually at #PointLowly to breed. The mass aggregation allows researchers to observe behaviors like #color changing and mimicry within the population.

🌊🦑 Sperm #whales consume massive amounts of colossal #squid, but we have rarely seen these giant #animals alive in the deep #ocean.

Researchers are now using environmental #DNA to identify species by filtering genetic material directly from seawater samples. The process helps track known animals and search for unknown organisms.

Did you know? 🌟 Octopuses boast 3 hearts and blue blood (copper haemocyanin), optimized for cold, oxygen-scarce marine realms. Two hearts serve gills; one systemic heart supports complex physiology + 9 neural centres (‘brains’)!
