"Can octopuses solve puzzles faster than humans?
Octopuses are known for their incredible problem-solving skills, often using tools and adapting to new situations. They have been observed escaping from complex enclosures and even opening jars to get to food.
Intelligence is not just about brain size, as seen in octopuses, but also about creativity and adaptability.
Have you ever seen an octopus outsmart its owner?

Swarm behaviour (Zoology 🦥)
Swarm behaviour, or swarming, is a collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving en masse or migrating in some direction. It is a highly interdisciplinary topic. As a term, swarming is applied particularly to insects, but ...

“Cephalopods such as octopuses, squids, and cuttlefishes have shown the capacity to learn and remember, to use tools, and even to engage in play. Instances of self-care and protective behaviors have also been documented. For example, octopuses have been seen wrapping their arms around an injured area, and cuttlefishes avoiding the claws of crabs after having previously been pinched.
Invertebrate beings such as lobsters possess nervous systems with receptors that detect harmful stimuli such as extreme heat, shocks, or physical injury. When boiled alive, they thrash frantically and attempt to escape—strong indicators of suffering. Research has also shown that lobsters living in enriched environments with objects to interact with and social company exhibit less aggression and stress.”

“Sentience—meaning the capacity to suffer and to experience enjoyment—is a crucial topic that invites us to reflect on how we regard aquatic beings. Are fishes aware of what happens to them? Although they often go unnoticed, a wide body of scientific evidence indicates that they can indeed feel pain and experience mental states similar to ours.
It has been observed, for instance, that trout are willing to endure a certain level of physical suffering that they would normally avoid, in order to socialize with others—something that seems to indicate that this is important to them.”
