10 unexpected facts about octopuses
Simulated octopus. Thaumoctopus mimicus, a species of octopus from the tropical seas of Southeast Asia, was recently discovered in 1998. Although many octopuses can change skin color, these guys went much further - they copy the appearance and behavior of more than 15 other sea creatures - stingrays, sea snakes, jellyfish, flounders, crabs and even sea anemones. Predators, counting on a certain behavior of prey, do not expect at all that it will turn out to be a pretending octopus.
Octopus Paul. The only clam awarded the British DAFTAS Awards in the category “The Most Extraordinary Animal Story”. Although the prophet octopus predicted Germany’s football results with high accuracy at Euro 2008 and with absolute accuracy at the 2010 World Cup, its “mystical gift” is due to ordinary luck. But he definitely attracted the attention of the planet to octopuses.
Autocannibalism. Octopuses can drop their own tentacles in case of danger, and then grow new ones. Some individuals were generally seen behind the frightening habit of eating their own limbs. It was not a lack of food and stress, but a strange disease that was still not recognized.
Fighting the octopus. That was the name of a specific sport in the United States, the unusually popular 1960s. According to the rules, the diver grabbed a large octopus and tried to pull him out of the water. Mollusks caught in this way could be eaten, sent to the zoo or simply released.
The skill of opening bottles. A female giant octopus (Enteroctopus dofleini) named Billie from the Seattle Aquarium is able to open baby food bottles, overcoming protection from children. When scientists arranged a test for her with time measurement, Billie was able to get food in just five minutes.
Coconut Armor. Octopuses are not very well protected, but their brains work fine. Some individuals look for two halves of a coconut shell and carry them with them, if necessary, hiding in them from danger.
Soaring octopuses. Females of soaring octopuses (genus Tremoctopus) exceed the males in size ... ten thousand times. Females reach two meters in length, when males do not grow more than two and a half centimeters. Males use their tiny size, hiding from predators among the poisonous tentacles of a Portuguese jellyfish jellyfish.
Short life. Most octopuses live no more than three years, some even die at the age of six months. The statistics are also influenced by the fact that soon after the reproduction in the octopus organisms, a “self-destruction mechanism" is launched, which kills them in a matter of months.
Adherents of purity. Many octopuses - those that have a permanent residence in small grottoes among the stones - maintain their homes in perfect cleanliness. With a stream of water, they sweep out all the garbage behind the “door”.
Features of the structure. Octopuses have nine brains - a nerve head node in the head and eight ganglia at the base of each limb. Three hearts - one for driving blood throughout the body and two gills for pushing blood through the gills. Their blood is blue due to the oxygen-carrying hemocyanin pigment.
