Humboldt squid (aka Jumbo Squid) are known to cannibalize each other and are especially likely to eat a squid that has been injured or hooked on fishing lines. They use sharp, barbed tentacles to cut apart their prey and then drag it to their mouth where a baseball-sized beak shreds it into edible pieces.
These squid are large enough to be a potential danger to human divers.
When threatened, squid will attack human divers and continue to put up a fight even after they've been caught, blasting their captors with ink and propelling water out of their funnel.
Like other cephalopods, jumbo squid can alter their coloration to match their environment, changing from white to dark red in an instant.
Humboldt Squid have been given the nickname diablos rojos by Mexican fisherman because of their aggressive reputation and ability to change colors.
Humboldt squid are social animals, sometimes swimming in school of up to 1,200 individuals.
Some squid species (including the Humboldt) can use their funnel to propel themselves out of the water to escape from predators. Their small fins allow them to glide over the water’s surface and “fly” through the air.
Humboldt Squid only live about one year (though larger individuals can live up to 2 years).
