Know more about octopus 🐙🦑

 Octopus are extremely intelligent. They can learn new things just like humans .They have even learned a few tricks to get them out of sticky situations. If an octopus is threatened by a predator, such as a shark , it can used some pretty incredible skills to get away. Octopuses don't have teeth or sharp claws to defend themselves. Instead , they use more clever ways to fool their attackers. Octopuses  like to hide themselves in the sand on the bottom of the ocean floor. Well ,the octopus is like a chamaleon because it can change the colour of its skin to match the sand.

And this colour change, or Camouflage, happens in less than a minute. Some octopuses like to stay in more shallow water where there are rocks and coral. Because octopuses are in- vertebrates, meaning they don't have backbones, they can squeeze themselves into small spaces between the rocks to get out of reach of their predators. Another way and octopus can hide is by shooting Ink. And octopus uses a part of its body called a  siphon to shoot ink into the water. The ink forms a cloud that hides the octopus. By the time the ink clears and the Predator can see again, the octopus has swum away or hidden. It's very much like a magician doing a vanishing act.

 If you think that's a need trick, then you'll love what else this creatures have their sleeves. If an octopus is being attacked ,it can actually make itself look like a venomous sea snake. It will bury itself in the sand ,keeping two arms visible. It will change the colour of those arms to match a sea snake. But what if there's no time to hide?  If an octopus is in trouble, it can break hope of one of its arms. The answer will then change coloured and screen around in the water to distract the Predator while the octopus swims away to safety. The octopus will grow back. 

There is one kind of octopus that has venom to use in defence.The blue ringed octopus is tiny; it could fit in the palm of your hand. Predators might think this size makes the octopus a great snack, but they know to stay away. The blue ringed octopus is very poisonous and can kill predators much larger than itself , including humans.

So the next time you see and octopus in the aquarium or while you're swimming under water, remember that inside that oversized head is a very large brain, making them a clever addition to the sea.
