Maximum length is more than 1.5 meters, weighs 40-50 kilograms, and swims up to 24 kilometers per hour. The Humboldt Squid is a nocturnal hunter with keen eyesight and a carnivorous appetite, feeding mainly on small fish, crustaceans, cephalopods and copepods. This species is highly aggressive and has a record of attacks on humans, making it quite dangerous. The Humboldt squid lives 1-2 years.
Humboldt squid live in the cold waters of the Humboldt Current in the eastern Pacific Ocean of Central America and are one of the 12 deadliest species there.
They have flesh-colored coats that are orange-red when caught ashore, are graceful and hideous in the water, and are used to hunting in schools of up to 1,200 individuals, who communicate with each other and their companions by rapidly changing the color of their own bodies, and who are intellectually advanced and have a complex communicative physiognomy. They come out by day and by night, attacking everything they eat, including humans, and are known locally as the "red devil diablos rojosr".
It has two huge eyes that can reach an average diameter of five centimeters, with vision 200 times better than that of humans in low light conditions, three hearts, blue blood, and eight tentacles, each of which consists of more than 160 muscles, with about 300 suction cups on them, each of which has a pulling force of 100 grams. The beak-like mouth and tentacles have mouths in the middle, which contain needle-like fangs that can paralyze or outright rip apart prey. They grow rapidly, with adults reaching a maximum length of 2.1m and weighing up to 90kg. fights occur when rounding up food and will eat each other.
Humboldt squid are schooling animals, which is different from the lifestyle of other squid. They communicate by changing the color of their body's light and can produce different light depending on the situation, thanks to light spots in their bodies, which they can change by shrinking the size of the spots.
While Humboldt squid are highly viable in water, they can only survive for a few minutes or hours out of the water.
