Why Octopuses are Considered the Most Intelligent Invertebrates
A creature of soft body, eight arms with one brilliant brain, short lived creature, yet it thinks in a certain way that rivals some mammals. It's an octopus that has around 500 million neurons which is somehow comparable to dogs and that is far higher than most invertebrates. This article is about their unique nervous system, problem solving skills, their art of camouflage, play, learning & evolution.
A Brain Like No Other
One fascinating thing about octopuses is that they have a highly distributed nervous system, so they have two-thirds of their neurons in their arms, not centralised in a single brain. Astonishingly, this gives each of their arms semi-autonomous control. Their arms can feel and act while the central brain can be busy in planning higher-level moves.
Problem-solving & learning
Octopuses can repeatedly open jars, remove lids and extract crabs which is a clear sign of trial and error or learning and memory. They can even navigate mazes and anecdotes of aquarium escape artists to illustrate applied problem-solving.
Another fascinating thing about the octopus is that their skin contains chromatophores, iridophores and leucophores which allow them to change their colour lightning fast, not only that, even their pattern and even texture to match backgrounds or mimic other animals.
Play, curiosity & individual personalities
There are captive octopuses that have demonstrated object play, repetitive non-functional interactions and they have shown curiosity toward keepers and toys. These are the behaviours that are interpreted as play and exploration. Note that octopuses individually show bold as well as shy temperaments which is a evidence of individuality and obivously an example of complex behaviour patterns. They like to play with objects in water and sekk validation or enrichment interaction.
The intelligence creature have their amazing survival strategy inside a predator-rich world. Octopus evolve and reminds us that brains don't need bones to be brilliant; it is evolution that finds its intelligence in the most unexpected forms.
