![]() ![]() Like other cephalopods, the Humboldt squid has a well-developed nervous system and has been observed in the wild exhibiting social behaviors such as communication and cooperative hunting, behaviors unseen in other invertebrate species. However, the Humboldt squid is much more than just a voracious carnivore. © Carrie Vonderhaar, Ocean Futures Society When distressed, the animals elicit a bright red color, giving them their infamous nickname from Mexican fisherman, “Diablo rojo” or “red devil.” Humboldt squid are also capable of rapid changes in the texture and color of their skin, which is mediated by specialized cells on their body called chromatophores. ![]() These animals possess extraordinary eyesight, a razor-sharp beak, and eight tentacles lined with hundreds of barbed-like hooks on their suckers, which they use to grasp and tear apart prey. Reaching lengths of up to six feet and weighing nearly one hundred pounds, the Humboldt squid is not only one of the world’s largest squids, but also one of the ocean’s most formidable predators. From nearly 2,000 feet below, the Humboldt squid begins its nightly journey towards the surface to feed on the plentiful array of prey inhabiting the shallow waters. It is important to note that jumbo squid populations have been increasingly migrating farther north than their normal range, in some cases as far north as Alaska.Carrie Vonderhaar, OFS chief expedition photographer, captured these amazing images while on expedition with marine biologist & OFS expedition diver, Holly Lohuis, in the Sea of Cortez.Īs the sun sets along the Sea of Cortez, curious creatures begin to emerge from the dark depths of the sea.

They also have the ability to squirt ink as a defense mechanism. Like other cephalopods, they are equipped with chromatophores and are able to change color and flash light to communicate. This name comes from their red hue when hooked, which is used as camouflage from predators in deep waters where most animals cannot see the color red. These elusive and mysterious creatures are aggressive predators, which has earned them the nickname “red devils” or “diablos rojos” (from Mexican shrimpers who fish for jumbo squid during the shrimping off-season). They have a large, tough, thick-walled mantle and long arms with 100-200 powerful hooked suckers on each and lightning-fast tentacles. Jumbo squid are large impressive squid (actually of average size considering all squid species) that can reach up to 2 m in length and weigh up to 45 kg. Jumbo squid are members of the flying squid family, Ommastrephidae, and are known to actually eject themselves out of the sea to avoid predators.
