(Natural News) The cephalopod class of mollusks – which include cuttlefish, squid, and octopuses – are considered intelligent invertebrates and are important examples of advanced cognitive evolution in animals.
Without exception, cephalopods are active predators that have the ability to locate and capture prey, which demands some sort of reasoning power.
There are more to squids than meets the eye: They are known to be able to count, solve problems, recognize patterns and even communicate through a number of signals.
How they see remains a mystery because they are technically colorblind. However, they do seem to perceive color in some way, as they instantly change colors on the upper and lower bodies to blend into different backgrounds or attract potential mates. This complex behavior has also drawn intense interest in researchers over the years.
Neurobiologist Wen-Sung Chung of the University of Queensland in Australia said that these cephalopods are approaching the complex brains of dogs, and are surpassing mice and rats, at least in neuronal number.
“For example, some cephalopods have more than 500 million neurons, compared to 200 million for a rat and 20,000 for a normal mollusk,” she said.
Squid brains, in particular, are known to be nearly as complex as dog brains, according to researchers. Using high-resolution MRI and various staining techniques, researchers discovered and described previously unknown major neural pathways in squids.
Cephalopod intelligence complexity
The complexity of cephalopod intelligence is fascinating. “These creatures are vision-dominant predators, and almost all coastal species are masters in doing dynamic coloration and camouflage based on direct control of the chromatophore cells all over the skin,” Chung said.
“One very famous case is about their visual communication during mating competition. Males can display a ‘skin powered’ alphabet and have physical fights to compete for the mate.”
Squids can even say “I love you” to their favorite partner, but using different ways. While it is certainly not an “instinct reflection,” they have a very complex cognition process in their brain.
