Intelligence is generally acquiring, comparing, retrieving, storing, combining, and conceptual skills and recontextualizing information. Octopuses are exceptionally intelligent invertebrates. The study of the intelligence of octopus also has an essential comparative aspect. Its nervous system is different from that of vertebrates.
The Coleoidea subclass is thought to be the most intelligent invertebrates and is an actual example of advanced cognitive evolution in animals. Within the biological community, the scope of octopus intelligence and learning capability is controversial.
Brain octopus –
Octopus has large, well-developed brains, and their brain-to-body mass ratio is the largest among the invertebrates. They fall between endothermic and electrothermic vertebrates. The nervous system is the most complex of all invertebrates.
Behavior octopus –
Octopus are active predators. They need to locate and capture their prey and be the evolutionary driving force behind their intellectual development. The staple food is crab, and they will seek out lobster traps and steal the bait inside. They also climb in the fishing boat and hide in the containers that hold dead or dying crabs.
Communications octopus –
The octopus is the most social animal. They communicate visually with many different kinds of signals. To produce these signals, they can very four types of communication elements: chromatic, skin texture, posture, and locomotion. Through the nervous control of chromatophores, some octopuses can rapid changes in skin color and pattern.
Things that octopus can do –
- They can bust out there their aquarium tanks and find their way back to the ocean.
- Through a hole, they can slip their entire body.
- From the inside and outside, they can open jars.
- With rocks, they can defend themselves.
- They can take apart the plumbing of their tanks, causing sweet, soggy mayhem.
- They can jump on land.
- For their amusement, they are known to turn on the light.
- Out of coconut shells, they can make tools.
- They can escape their tank to eat fish in an adjacent tank and return back without anyone noticing.
