What is this? Humboldt Squid are more likely to attack objects or species that appear foreign, especially when those objects could pose a potential threat to its shoal (group of traveling squid). There have been confirmed Humboldt Squid attacks on human beings in the past, especially on deep sea divers.
Small squid often hunt in groups. Squid mainly eat crustaceans, crab, shrimp, orange roughy, hokie, oysters, lantern fish, and other small fish. They are known to be cannibals. They often prey on other smaller squid for food, although only in extreme situations.
Giant squid mostly eat deep water fishes and other squids—including other giant squids. They also will attack schools of fish from below, quickly ascending into shallower waters to grab a meal before retreating to safer depths away from predators.
The mysterious and mythical giant squid has never been spotted alive in the deep sea -- until now. A team from Japan's National Science Museum has captured footage of a giant squid in its natural habitat: nearly a third of a mile below the surface of the ocean. It is the first such video of its kind.
Despite his name, Squidward Q. Tentacles—the grouchy neighbor of SpongeBob SquarePants in Nickelodeon's long-running cartoon—isn't a squid. He's an octopus. (Allegedly, creator Stephen Hillenburg named him Squidward because “Octoward” sounded too weird.)
Squids have eight legs of a uniform length, and two longer tentacles with sucker pads for grabbing prey. The head and body of an octopus visually blend into one form, whereas the separation between body parts is much more defined on squids.

You wouldn't be alone if you thought the octopus and squid were the same animals. They are cousins—both part of the group cephalopoda—a group of marine mollusks that include squid, octopus, nautilus, and snails. The largest cephalopod is the giant squid and the smallest being the pygmy squid.
Inside the giant squid's sharp beak is a tongue-like organ called the radula (shown in yellow). Covered with rows of tiny teeth, it rams bite size pieces of food down the squid's throat. The pieces must be small because the giant squid's esophagus passes through the brain on the way to the stomach.
Squid have three hearts: two branchial hearts and one systemic heart. The branchial hearts pump blood to the gills, where oxygen is taken up. Blood then flows to the systemic heart, where it is pumped to the rest of the body. The systemic heart is made of three chambers: a lower ventricle and two upper auricles.
Despite reports of giant squids exceeding 18 metres (59 feet) in total length, the maximum total length of examined specimens is roughly 13 metres (about 43 feet), with a mantle length (that is, the length of the mantle and head only) of more than 2.25 metres (7.4 feet).
Each squid can have up to 35,000 teeth. These sharp teeth bite through protective swim gear to grasp and tear flesh. Squid with claws can rip and tear through your suit and skin.
The colossal squid
The colossal squid is incredibly large with a weight of at least 1,090 pounds and a length estimated between 30-33 feet. This size makes the colossal squid the largest squid in the world.
Squid have short lifespans, and most species only live for one to three years. While scientists don't know exactly how long giant squid live, they believe it is no more than five years so they must grow very quickly, according to the Smithsonian.
Suspended from the squid's arms by hooks, the female squid carries her brood of roughly 3,000 eggs with her to keep them safe at depths of 5,000 to 7,000 feet (1,500 to 2,500 meters). She uses her tentacles to push water through the egg cases, providing them with oxygen.
The hatchlings are called paralarvae, a term that was invented to describe all baby octopus and squid. A true larva, like a caterpillar, goes through cataclysmic metamorphosis, which octopus and squid do not.
The squid is nocturnal and relies on the bacteria bioluminesce. This relationship is mutually beneficial. The bacteria gets a place to live, food and help reproducing. The squid gets a nice light show that helps to camouflage it from predators.
An octopus has up to 9 brains! Yes, you read that right, 9. Around two-thirds of its brains are located in its arms with the rest commonly in a doughnut shape around its oesophagus.
Do squid have balls? Do you mean tentacles (= none; this is a characteristic of squid) or arms (= 8). They have nothing akin to the mammalian testicle, but they do possess a single testis sac, accommodated within the mantle of the animal.
