                                               Facts about Octopus

Octopuses are spineless but colorful sea-dwelling beasts that have been around for ages keeping life in the ocean interesting. They are also considered one of the most intelligent animals in the world. An octopus has eight arms, hence its name, because in Greek, ‘okto’ means eight. It has total three hearts, one large one and two smaller ones. Their blood is blue in colour. Approximately two-thirds of an octopus’s neurons reside in its arms, meaning they can react to stimuli and function on their own even when detached from the body.

Quick Facts: –

  • There are approximately 300 known species of octopus found throughout the world.
  • They can easily change their texture and color of the skin to camouflage with the environment and become invisible.
  • Since they have no bones in their bodies, they can squeeze through the tiniest of cracks.
  • Octopus ink contains a compound called tyrosinase which helps to control the production of the natural pigment melanin in humans.
  • They release a cloud of black ink to obscure their attacker’s view. It gives them time to swim away.
  • Their skin contains the same light-sensitive proteins present in their eyes so they can see with their skin.
  • Rather than swimming, they often walk along the seafloor.
  • Females lay about 150,000 eggs in a week. These eggs require about 3 months to hatch.
  • An octopus can also lose an arm if required to escape a predator’s grasp and then re-grow it later.
