The Strange Anatomy of a Squid

Squids are among the most unusual creatures in the ocean, with some species reaching up to 40 feet in length, and weighing more than 1,300 pounds.

  • How do squids handle the extreme pressures at such depths?
  • What’s their connection to dinosaurs?
  • The answer to all of these questions and more can be found here, with our guide to squid anatomy!


Learn about Octopuses

In order to write intelligently about squid anatomy, you’ll first need to know what octopuses are. Octopuses are similar to squid in that they have eight arms and two tentacles. This distinct difference can help you to remember that octopuses have eight arms and squids have ten.


What do squids eat?

Squids are carnivores, meaning they feed on other animals. Most squid species have teeth in their mouths that they use to capture and subdue their prey, which includes fish, shellfish, crustaceans, worms and even small octopuses. Larger squid species may attack and eat small whales or seals! Their tentacles are covered with suckers that help them catch prey. In fact, each sucker has its own jaw!


Amazing Facts about Squids

Did you know that some squid species have more than ten tentacles, or arms? While most squid have eight or ten tentacles, colossal squid (genus: Mesonychoteuthis) have two long tentacles and up to four shorter ones. The largest ever found had hooks 1.25 m (4.1 ft) long! How about other strange facts?


How old can squids get?

Squids are believed to be one of nature’s oldest creatures and, like octopuses, squids also have an extraordinary lifespan. The average lifespan for an adult squid is typically between 4-6 years, though some can live much longer depending on their environment. For example, Humboldt squids in captivity can live up to 16 years.


Where are they found?

Squids live in oceans throughout the world, with deep-sea species ranging from bathypelagic to abyssal. Many squid inhabit tropical shallows and coral reefs or lagoons. The largest known is believed to be Colossal Squid living at depths up to 3,000 meters below sea level.


Are there any species of squids that attack humans?

Are there any species of squids that attack humans?


While most squids are relatively harmless to humans, one species, Humboldt squid, has been known to attack people who they feel are threatening their safety. This large squid can be found in tropical and subtropical waters throughout South America. They have been known to grow up to three meters in length (almost 10 feet) and weigh almost 45 pounds!


How are squids different from octopuses?

Despite their many similarities, there are many differences between squids and octopuses. While both cephalopods have eight arms with two rows of suckers, squid also have two tentacles while octopuses only have one. Squids’ bodies are tubular while octopus’s torsos can be described as sack-like, and squid also don’t have shells like their cousins do.


Meet the Giant Squid

The giant squid, which can grow up to 40 feet long, is sometimes described as being like an octopus on steroids. It has eight arms, but only two tentacles (although these tentacles can be much longer than those of its cephalopod cousins). These appendages are lined with rows and rows of sharp, hooked suckers.
