Common Name: Giant Squid
The giant squid is a deep-sea organism, found in oceans all over the world. Its habitat may include waters as deep as 3,000 feet or more.
Giant squid prey includes fish and other, smaller squid species. It is believed they spend most of their time alone, though little is known about much of their habits due to their deep water habitat.
Predators of the giant squid include pilot whales, sleeper sharks, orcas, and (most famously) sperm whales. Sperm whales are often seen with circular marks and scars on their massive heads, left by giant squid suction cups. While these two giant ocean predators are often depicted in paintings and life-sized museum models engaging in epic battles with each other, the truth is the actual nature of their conflict has never been observed in the wild. However, based on the stomach contents of sperm whales, the whales nearly always seem to be the victor.
Due to their secretive nature and the difficulty of studying the animals in their deep-sea home, not much is known about the reproductive process of the giant squid. It is known that females lay an enormous amount of eggs, sometimes over 11 pounds worth, each egg measuring barely a single millimeter long.
The giant squid is an extremely large squid that can measure over 40 feet in total length, from the fin at the end of its main body (or mantle) to the tip of its two longest tentacles. The mantle itself can measure over six feet long.
The giant squid’s body is reddish pink in coloration and consists of an arrow shaped mantle, eight arms, and two additional extended tentacles. The arms feature suction cups on their underside, while the tentacles are thinner and only feature suction cups at their clubbed ends.
The squid’s mouth is a beak found at the center where its tentacles meet. Its eyes are the largest in the animal kingdom. Each eye can be up to 10 inches across.
For a long time, the giant squid was a creature of legend, and only fairly recently have living examples been captured in photos and on video.
The squid has been referenced by Aristotle in 4th century B.C., and Pliny the Elder in 1st century A.D. Stories and legends of the massive squid shared by sailors may have been the inspiration for the mythical beast known as the kraken, as well as other fantastical sea monsters.
In the 1800s, strandings of squid on the shores of Newfoundland and New Zealand led to a better understanding of the animal by scientists.
It wasn’t until 2001 that the very first images of a giant squid were captured on film, although it was not the massive adult squid that was filmed, but the tiny larval (baby) form. The first photo of a live adult giant squid was taken in 2002 off the coast of Japan. Found near the water’s surface, this squid was believed to be in poor health and died soon after it was encountered.
The first photos of a live adult giant squid in its natural habitat were captured in 2004, again off the coast of Japan. These photos gave insight into the hunting behavior of the giant squid. The first video of a living adult squid was captured in 2006, off the Gulf of California in Mexico. A juvenile giant squid was also caught on film in the Gulf of Mexico in 2019.
Its elusive and legendary status has led the giant squid to be featured as a monstrous and frightening beast in many books and films throughout the years, including Jules Verne’s 20,000 Leagues Under the Sea.
Giant squid are a species of Least Concern. Due to their deep-sea habitat, encounters between humans and giant squid are extremely rare.
