What is an ocotopus?
Octopuses are cephalopod mollusks that live in oceans all around the world.
Octopuses have 8 legs (tentacles) that are lined with suction cups.
An octopus body is soft- it has no skeleton, the only hard part being its beak-like mouth.
Octopuses have 3 hearts- one main heart and two smaller hearts by its gills.
All octopuses have venom, but only the blue-ringed octopus is potentially deadly to humans.
Octopuses have a number of ways to protect themselves. They are fast swimmers that can hide in small spaces. They can also eject ink from their bodies that help them hide and also make it harder for predators to smell them.
Octopuses are considered to be the most intelligent of all invertebrates.
