As you will see in these octopus videos, they are much more than slimy brainless creatures. Octopus can learn, use tools and extraordinary defense mechanism. You will be blown away by these unique octopus videos. - An octopus can flatten its body down and squeeze through the tiniest of openings. An opening the size of an apple is large enough for an octopus that weighs over one hundred pounds and measures over ten feet in length to squeeze through. They can do this so easily because they are invertebrates, or animals without backbones. In fact, an octopus doesn't have a single bone in its body. Other than its hard bird-like beak, its body is entirely soft. - At the slightest hint of danger an octopus can immediately swim straight home, even if it had been wandering aimlessly for hours. They can do this because they have amazing short-term and long-term memories, and can recall environmental landmarks with ease. An octopus is a master of camouflage. At a moment's notice it can change its color and texture to match its surroundings. Some species can even change their appearance to look like the predator of the animal that was about to eat them. - It is well-known that an octopus can eject a blackish ink when in danger. The ink clouds the water and makes it easier for the octopus to quickly escape. Along with making it harder to see, the ink cloud also reduces the predator's ability to smell. Sometimes the predator is so confused that it even thinks the ink cloud is the octopus and attacks that. - It takes more than just a desirable body to be a master of escape though. Luckily, octopuses are also extremely intelligent animals. An octopus can open latches and screw lids off jars. A few have even figured out how to open empty pill bottles that have child safety lids. Some of the scientists studying them have a hard time doing this.
