Octopus at SEA LIFE

Which creature has three hearts, eight arms and a doughnut shaped brain? You guessed it: it’s the octopus!

Octopus are mollusks, which means they are from the same phylum (or family) as slugs, snails, cuttlefish and squid. They are well known for being very clever. In fact, they are one of the most intelligent invertebrate species (that means animals with no backbone). Generally, octopuses are solitary creatures that hunt at dusk.

The Octopus is one of the most amazing creatures in the sea!

  • No Bones? No Problem! Just like our sharky friends, octopus have no bones!
  • Having no bones makes these cunning predators hard to evade because they can squeeze into tiny nooks and crannies to get to their dinner. As long as the gap is large enough for their eyeballs, then they can fit!
  • They can also change the color and texture of their skin to camouflage perfectly with their surroundings, helping them to sneak up on prey as well as hide from predators.
