The scientific name for octopus is Octopoda, and there are about 300 different species. There are over 85,000 different species of mollusks!

The main difference between an octopus and a squid is their diet. And finally, octopuses are not as long-lived as squids-they typically only live for about 1-5 years, while squids can live for up to 10 years or more. They often live alone in dens that they excavate from the seafloor, while squids tend to live in groups called shoals. Octopuses also tend to live at shallower depths than squids-they’re commonly found in reefs and tide pools, while squids are found in the open ocean.Īdditionally, octopuses are more solitary creatures than squids. They can be found in tropical and temperate regions, while squids are mostly found in cold waters. For one, octopuses live in warmer waters than squids. Octopuses can release a cloud of ink to confuse predators, while some species of squid can release a bright burst of bioluminescent light to startle and distract predators.Īn octopus and a squid may look similar, but they have some key differences in their habitat. Squids are more social and often travel in schools.īoth octopuses and squids are known for their ability to change color and shape to blend in with their surroundings, but they have different defense mechanisms as well. Octopuses are generally solitary creatures that spend most of their time hiding in crevices or burrows on the ocean floor. Also squids are generally larger than octopuses, with some species of squid reaching lengths of over 40 feet, while most octopuses are less than 1 meter in length. Instead, octopuses have rows of suction cups that can be used to grasp and manipulate objects.Īnother difference is that squids have two long tentacles that are used for catching prey, while octopuses lack true tentacles and instead have eight arms that are used for both locomotion and grasping prey.
