The Humboldt quid is also known as the jumbo squid or jumbo flying squid in English and in Spanish as calamar gigante or jibia or pota. They have a propensity for rapid flashing of the colors red and white when captured and because of this are also known as diablo rojo ('red devil'). It is the largest of the Ommastrephid squids, with some individuals reaching 1.5 m (5 ft) in mantle (body) length and weighing upwards of 50 kg (110 lb). The mantle makes up at least half of the animals mass and includes the fins or wings. The remaining portion is roughly split between the arms and tentacles and the head (including eyes and beak). They possess two tentacles each carrying between 100 and 200 suckers. The suckers are lined with razor sharp teeth or hooks which they use to grasp prey and drag it toward their very large and very sharp beak.

They often approach prey quickly with all 10 appendages extended forward in a cone-like shape. Upon reaching striking distance, they open their eight swimming and grasping arms, and extend the tentacles covered in sharp hooks, grabbing their prey and pulling it back toward a parrot-like beak, which can easily cause serious lacerations to human flesh. These two longer tentacles can reach full length, grab prey, and retract so fast that almost the entire event happens in one frame of a normal-speed video camera. Each of the squid's suckers is ringed with sharp teeth, and the beak can tear flesh, although they are believed to lack the jaw strength to crack heavy bone. The squid are known for their speed at eating; they feast on hooked fish, stripping them to the bone before fishermen can reel them in. Their behavior while feeding often includes cannibalism and they have been seen to readily attack injured or vulnerable squid in their shoal. Until recently, claims of cooperative or coordinated hunting were considered unconfirmed and without scientific merit. However, more recent research has strongly suggested they do engage in cooperative hunting.

They live in shoals which can be as large as 1,200 individuals and can move incredibly fast, upwards of 15mph, propelled by water ejected through a hyponome (siphon) and by two triangular fins. The ejected water generates enough force to send them them flying out of the seas to heights as far as 10 feet or more above the surface. It is this ability to "fly" that has been the source of many myths and legends among the men who fish for them. The legends speak of colleagues or friends "dragged down to the briny depths" by hunting Humboldts flying out of the water and snatching a man who was too close to the edge or not paying enough attention to his surroundings and situation. In some cases it is said the men were first hypnotized by the flashing lights of the squid, putting them into a trance like state and immobilizing them, making them easy pickings for the squid. It is this color generating (chromogenic) behavior that has been the source of most of the mythical stories specific to the Humboldt squid. Those tales tell of men not dragged down to the briny depths against their will by squid flying out of the water to snatch them, but rather of men who willingly (of a sort) give themselves to the squid, walking or running or jumping from the sides of their boats directly into the maws of the waiting, hungry squid. The belief is that these men were compelled to their deaths by one or more Humboldts who used their flashing lights to "hypnotize" and "trance" them and force them to feed themselves to the squid.

Humboldt squid have two modes of colour-generating behaviour: The entire body of the squids "flash" between the colours red and white at 2–4 Hz when in the presence of other squid, this behaviour likely represents intraspecific signalling. This flashing can be modulated in frequency, amplitude and in phase synchronisation with each other. What they are communicating is unknown – it could be an invitation for sex or a warning to not get too close or, if the legends are to be believed, a hypnotic signal which can induce a trance like state in their potential prey, including humans. Once induced into trance the prey is immobilized and helpless, or in some cases actively moves in the direction of the squid, accelerating its own demise. The other chromogenic mode is a much slower "flickering" of red and white waves which travel up and down the body, this is thought to be a dynamic type of camouflage which mimics the undulating pattern of sunlight filtering through the water, like sunlight on the bottom of a swimming pool. The squid appear to be able to control this to some degree, pausing or stopping it....these two chromogenic modes are not known in other squid species.

Fishermen Julio Ramirez was known among the locals in the small fishing community in Baja, California Mexico where he lived as a historian of the Humboldt. He knew as much about the squid, and the legends about them as anyone. He had seen men tranced by the squid before, it had happened to himself once many years ago. However, in the cases he had seen, and in his own, the trance had resulted only in a brief period of immobility. It had not lasted more than 10-15 seconds. Now, however, he found himself unsure of where he was or what exactly he was doing. It felt like he was walking and he had a vague sense that maybe he shouldn't be, or that he was heading in the wrong direction. But everything seemed so hazy and fuzzy and light and he was tired, so very tired. He just wanted to lay down and go to sleep. Suddenly he saw flashing lights below him and all around him. They were so beautiful, and he somehow knew they would show him where he could rest. Lead him to where he could sleep. Something in the back of his mind protested, and he thought he heard voices or shouts of wait and no, or something like that, but it was all so far away, so distant. He needed to rest, he was sure of that much, and he took one more step forward.
