Squids can be said to have a high IQ, although squids don't have an IQ in the way humans have an IQ.
Still squids are very intelligent and among the smartest invertebrates in the world.
A squids intelligence is on par with dogs as squids also feature and have highly developed brains as well as strong memorization skill sand even remarkable abilities to coordinate camouflage and group behavior.
Although squids are highly intelligent creatures, a squids cognitive strengths also differ notably from animals like humans and octopuses.
Many types of squids like the reef squid and Humboldt squid also hunt and travel in large schools, and they possess advanced communication skills.
The squids also use intricate and rapid color changes that they can do through pigment cells that are called chromatophores to communicate feeding strategies and dominance hierarchies.
Squids also have different sets of skills than that of octopuses.
Squids have not been shown to solve any complex manual puzzles like jars, but they also vastly outperform octopuses in complex social coordination.
Octopuses are also solitary and also excel at manual tasks, such as unscrewing jars, using tools and solving of puzzles.
Squids also have nervous systems that are incredibly adaptable and can also dynamically edit their own genetic instructions at the RNA level, which scientists also believe is what fuels the squids rapid adaptation and complex behavior.
And so octopuses are widely considered more intelligent than squids.
Although both squids and octopuses are incredibly smart invertebrates, octopuses also possess superior problem solving skills, are able to use tools, navigate complex mazes and even display remarkable spatial awareness in their varied environments.
The intelligence of these cephalopods also varies greatly depending on how they live and hunt.
The Octopus (The Analytical Problem Solver)
Environment: The octopus is benthic (living on the seafloor), which requires navigating complex, three-dimensional coral reefs and rocky crevices.
Abilities: Octopuses are renowned as the smartest invertebrates on Earth.
Octopuses can unscrew jars, escape locked tanks, recognize individual humans, and use tools.
Nervous System: An octopuses nervous system is a decentralized marvel.
About 60% of an octopus's neurons are distributed throughout its arms, allowing each arm to taste, touch, and move semi-autonomously.
The Squid (The Social Communicator)
Environment: The squid is pelagic (living in the open ocean).
Their 3D open-water environment is often less varied, relying on speed and instinct rather than complex spatial memory.
Abilities: While squids rarely display the same puzzle-solving or tool-using feats as octopuses, they excel in social intelligence.
Social Dynamics: Many species of squid, like the Humboldt squid, are pack hunters that communicate and coordinate attacks using highly complex, rapid changes in skin color and patterns.
