Octopus is a sea animal famous for its round body, bulging eyes, and eight arms. Like sharks and jellyfishes, we can find octopus in all the world’s oceans. But, this amazing creature is especially abundant in warm, tropical waters. Like their cousin, the squid, octopuses are often considered “monsters of the deep”!

How big is an octopus?

Well, this animal varies in lots of sizes. First we have the smallest one, Octopus wolfi, who can grow only two inches. But, don’t let that confuse you, because the largest octopus can grow up to 18 feet and weigh 33 pounds! This big fella, the giant Pacific octopus, has an arm span up to 4,3 metres! Wow! Imagine you find yourself near this giant, it would be quite a challenge not to fall into his arms, right?

Feeding and fearless hunting.

Since this incredible animal lives deep in the dark ocean, it eats crabs, shrimps and lobsters. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth. The octopus performs its famous backward swim by blasting water through a muscular tube on the body called a siphon. Moreover, they also crawl along the ocean’s floor, tucking their arms into small openings to search for food.

Don’t mess with an octopus.

If you threaten this monster, it will fight back! How? By shooting an inky fluid that darkens the water, confusing the aggressor. The octopus can also change to gray, brown, pink, blue, or green to blend in with its surroundings. Along with that, one more reason of changing color is to communicate with other octopuses. This solitary creature lives alone in dens built from rocks, which he moves into place using its powerful arms.

High intelligence.

Oh, yes, our friend is very intelligent! Despite the changing colors, which comes from its brain, an octopus can even memorize and learn things! In laboratory experiments, octopuses can be readily trained to distinguish between different shapes and patterns. Heck, they even play! Like dolphins, octopuses have been observed playing with bottles and toys.

Did you know these intelligent monsters can even develop a speed up to 24 miles per hour?
