These clouds make predators confused and let cuttlefishes escape. They can also create clouds with sepia ink when they’re under threat. Cuttlefishes come with more camouflage as they can mimic coral and seaweed shape and texture.Ĭuttlefish species actively hunt for mollusks, fishes, crabs, and sometimes even other cuttlefishes. They can show bright, flickering patterns of color across their bodies on certain occasions.

Most of these creatures also boast the ability to change colors or skin texture instantly. Cuttlefishīelonging to the same subclass as squids and octopuses, cuttlefishes have eight short arms and two tentacles. Nautiluses live in the Indian and Pacific oceans, and can be found in the coastlines of Fiji, Japan, Australia, and New Caledonia, among other locations. Nautiluses are the Nautilaceae superfamily’s only living descendants, which is why some scientists consider them to be “living fossils.” Their lifespan can reach up to 20 years or more. The shells on young nautiluses typically have four chambers at birth, which expand as they grow. This species boasts a beak, eyes, and up to 90 tentacles that protrude from a large, round central shell.

While the Nautilus isn’t nearly as famous as the octopus and squid, it is just as remarkable. Scientists deem most of them to be highly intelligent they can even hunt or catch food with fellow squids on certain occasions. Squids can also change their color and swim faster than any other invertebrates. Some of their unique characteristics and abilities include backward swimming, which involves pushing water out from their bag-like bodies. But what makes squids distinct from their fellow cephalopods? Like octopuses, these creatures have eight arms that are relatively short compared to their large heads. You can find octopuses all over the world’s oceans. They can also fend off predators by squirting ink. They can measure anywhere from a few inches to several feet and can weigh hundreds of pounds.īesides multiple arms, these class Cephalopoda examples have three hearts and blue blood. They have bulbous heads and eight arms, and vary greatly in size and weight. 10 Cephalopod Types Living in Oceans WorldwideĪside from being one of the most recognizable cephalopods, the octopus is also one of the ocean’s most intelligent creatures. Let’s take a look at 10 kinds of cephalopods that you can find throughout the world’s oceans. But despite this fact, each cephalopod species shares the same characteristics. The term comes from a Greek word that means “head-feet.” There are five main types, or subclasses, of these creatures with several unique species under each subclass. Cephalopods are a class of mollusks that are distinguished their bilateral symmetry, large heads, and numerous tentacles.
