But finding the giant squid when they were no bigger than a fingernail was gruelling and expensive work. Everyone could enjoy it and experience the thrill of seeing this animal alive in person, rather than vicariously through the television screen.
It was only recently discovered that 21 different species of giant squid all shared the same DNA and were in fact the same species — does that suggest their population plunged and then recovered from a genetic bottleneck?

Squid beaks are made out of hard chitin, the same material as insect exoskeletons, with sharp edges that are perfect for chopping up prey into bite-size chunks, according to the AMNH.

Colossal squid Mesonychoteuthis hamiltoni live in the Southern Ocean at depths of at least 3, feet m and have larger and heavier bodies than giant squid, according to the Museum of New Zealand Te Papa Tongarewa. One of the few known colossal squid specimens, held at the Te Papa museum, weighs pounds kilograms , while giant squid are thought to only weigh up to about pounds kg.
Colossal squid can reach lengths of 45 feet 14 m , but giant squid can grow even longer because of their two elongated tentacles, and may reach 66 feet, according to the Smithsonian. Giant squid can be found in oceans around the world at depths of at least 2, feet, but their exact geographic range is unknown.
Some scientists believe that giant squid should be split into multiple different species, including separate species for populations in the North Atlantic, North Pacific and Southern Ocean.
However, a study published in the Proceedings of the Royal Society B analyzed 43 giant squid samples collected from across their range and found little genetic diversity. This suggests giant squid are a single species and intermingle through migration. Related: Giant squid all one big, happy family. Learn about it's massive eyes, sharp beak, and long hooked tentacles.

Watch: the mysterious world of the colossal squid Habitat Colossal squid live in Antarctic waters, but may come as far north as the southern waters of New Zealand. How common are colossal squid? Tsunemi was on a roll. In , his team published the first video of a live giant squid. It was relatively small, at pounds and 11 feet long, but it was the first moving pictures of the creature. In , a 6. With its tentacles it measured 26 feet — the same length as a bus.
Tasmanian Museum curator David Pemberton said it was one of the biggest ever discovered. The squid was thought to be feeding on grenadier fish in Australia's cold winter waters. In , the giant squid was recorded in its natural habitat for the first time. The trick to it was using a camera, designed by marine biologist Edith Widder, which emitted a blue light, like the light produced by a type of jellyfish known as Atolla.
The squid they caught on camera wrapped itself around the camera, and confirmed to the scientists that it was a predator. Widder told the BBC there were probably millions in the oceans, since they kept so many sperm whales fed. It's because humans scared them off that more hadn't been seen. So, knowing this, she designed a camera without thrusters or a motor. The only illumination was red light that's invisible to deep-sea animals, because they have adapted to primarily seeing blue.
O'Shea was on board for the momentous occasion. More evidence was gathered in , when a young female giant squid weighing pounds washed up dead on the Bares peninsula in Spain.
Its death pointed to the possibility that giant squid kill each other for food piracy. In June , about miles southwest of New Orleans in the Gulf of Mexico, the first giant squid was caught on camera in American waters. Nathan Robinson, who headed the team, found the clip after reviewing 20 hours hours of footage. The discovery was important, because the giant squid was filmed not far from one of the largest deepwater oil rigs in the world. They're part of our land, they're part of our country," Johnsen told The Times.
For now, the largest recorded giant squid measured up to 43 feet. Their cousin, the colossal squid, can grow up to 45 feet long, but scientists think giant squid can grow up to 66 feet. Both colossal and giant squid have the largest eyes on the planet, up to 12 inches wide — as big as a basketball.
Scientists think it's because they're necessary to see clouds of bioluminescence, which let them know when a sperm whale is approaching. Their sharp beak in the center of their arms slices its prey into little pieces, which are then ground down by a tongue-like organ covered in teeth.
When the giant squid was filmed in , it didn't shred the bait, as expected, but took small bites, slowly consuming the shrimp, so it didn't choke. Giant squid have eight arms, and use two long tentacles to seize their prey.
But their tentacles don't have any muscle to constrict prey.
