Biologically, squid belong to the class of mollusks known as cephalopods, which also include octopus. Squid are decapods, having 10 tentacles, compared to the eight arms of octopuses. They also are free-swimming creatures and exhibit schooling behavior similar to many species of fish.
Most researchers believe Humboldt squid live for only one year, but there is some evidence they may live to age 4. During this time they may grow to a length of 7 feet and weigh 100 pounds.
