Eyeless deep sea octopus. Octopus dumbo
Octopus Dumbo or Grimpoteuthis (lat. Grimpoteuthis), is a deep-sea inhabitant, living at depths of 100 to 5,000 meters, although some species have been found at depths of 7,000 meters. This is the deepest point for deep-sea shellfish.
It is known that in nature there are about 37 different varieties of Dumbo octopuses, classified into 4 families, which, as a rule, live in close proximity to the ocean floor. Octopuses that reach adulthood reach 20 cm in length.
Compared to other shellfish, the Dumbo octopus is a surprising species of the octopus family, as it prefers to swallow its prey whole. The bottom-dwelling species of Dumbo octopus feed primarily on crustaceans, worm-like animals and bivalves. Pelagic copepods make up the diet of that species of octopus that lives at a considerable distance from the ocean floor.
The Dumbo octopus is a soft-bodied or semi-gelatinous deep-sea animal that gets its name from the two fins located on the mantle, on the membrane between the legs, resembling elephant ears. The octopus can emerge directly from the surface of the bottom and seem to hover above the seabed, looking out for snails, worms or other prey.
By pulsing its webbed feet, pushing the water through the funnel for jet propulsion, the octopus moves through the water, helping itself with its large fins. When it is necessary to quickly overtake the prey, the speed of this waterfowl becomes terrifying, and with the same amazing speed the octopus can disappear from the predator pursuing it.
The Dumbo octopus is a rare species of eight-legged animal that can shed a transparent layer of skin at will and is an oceanic animal, like all other octopuses that have antennae. Few people are aware of the fact that males and females of the Dumbo octopus differ in size, as well as patterns on their suckers. However, there is some speculation that males may sometimes differ from females in the size of their suckers.
Males transfer masses of seminal fluid, so-called spermatophores, into the mantle cavity of females, thus fertilizing them. Each egg, attached to a substrate at the bottom, is incubated individually by a female octopus. Typically, octopus eggs are large in size, and the newborn octopuses that hatch may appear quite mature at the time of brooding. The ovaries of hatched octopuses contain eggs at various stages of maturity, suggesting that eggs are laid on a regular basis rather than in a specific season.
Octopus Dumbo (lat. Dumbo Octopus) or Grimpoteitis as they are scientifically called, or Grimpo, is a deep-sea octopus, found at considerable depth in large bodies of water such as the ocean, ranging from 100 to 5,000 meters, although some species of Dumbo octopus have been found at depths of 7,000 meters below sea level . This is the deepest point for deep-sea shellfish.

This species of octopus has not yet been fully studied, but one thing is clear: they are not endangered.

Octopuses– the most famous and most mysterious of the cephalopods. Their eight writhing limbs have always evoked thoughts of otherworldly origins, even inspiring artists, designers, and fascinating humanity since they began to explore the depths of the ocean.
THE ONLY SOLID PART OF THE OCTOPUS' BODY IS THE BEAK, LIKE A PARROT'S BEAKE. The rest of the body is unusually soft, flexible and elastic. It allows the octopus to penetrate the narrowest crevices and holes in rocks and reefs. Octopuses are found in all the oceans of the world, and science knows about three hundred of their species. They live only in salt water. Octopuses that live in warm waters tend to be smaller than species that live in cold waters. Their largest species, the giant octopus, lives in the Pacific region and weighs about 180 kg.
Octopuses are very peculiar and unique. They have three hearts! One, the main one, drives blue blood throughout the body, and the other two, gills, push the blood through the gills. Octopuses are capable of perceiving infrasound. They also hear ordinary sounds, despite the absence of ears. They are capable of throwing away a tentacle, breaking it on their own in case of danger, just as lizards throw away their tail. When trying to hide from the attacker, the octopus throws a cloud of ink into his eyes, and while the disoriented predator is in complete shock, the octopus successfully makes its legs.
Octopuses breathe through gills, but being out of water for a long time does not cause them serious harm. Some species of octopuses are able to temporarily leave the water and move on land, pushing off with their tentacles. The purpose of their exit from their native element can be either to search for prey in small puddles that remain after low tide, or to escape from larger predators. It's hard to imagine, but octopuses have rectangular pupils! Moreover, the eyes of octopuses are capable of expressing emotions of fear, anger, and joy.
A frightened octopus turns white, an angry one turns red. Octopuses taste with their tentacles. Each of the 8 tentacles contains more than 10 thousand taste buds that determine the edibility of a particular item. Almost all octopuses are capable of changing color, camouflaging themselves with their environment. This occurs due to the presence in their skin of cells with various pigments, which stretch or contract under the influence of impulses from the central nervous system.
Many zoopsychologists consider octopuses to be the smartest among all invertebrates in many respects: they are trainable, have a good memory, distinguish geometric shapes - a small square is distinguished from a larger one; a rectangle placed vertically from a rectangle placed horizontally; a circle is from a square, a rhombus is from a triangle. They recognize people and get used to those who feed them. If you spend enough time with an octopus, it becomes tame. These animals are highly trainable. Octopuses are clean people: they “sweep” their home with a stream of water from a funnel, and put scraps outside in a garbage heap.
AMONG THE MANY VARIETIES OF OCTOPUS THERE IS ONE, which is different from the rest. As it turned out, not only terrible and scary monsters live in the depths of the sea, but also quite unusual, cute creatures, for example, such as a small eared octopus, discovered by scientists recently at the bottom of the Gulf of Mexico. This is the Grimpoteuthis octopus. They live in great depths of the ocean, their specimens have been found as deep as 7,000 meters, although they usually live at depths of 100 to 5,000 meters. Later it became known that these extraordinary animals live in all 4 oceans of the planet. It is noteworthy that they come in different sizes, from small to impressive. Among them you can find a tiny one, which even in adulthood reaches a length of 20 centimeters, but the largest ever recorded representative of this genus was about 180 centimeters long and weighed about 6 kilograms.
This peculiar and funny animal is characterized by appendages on the upper part of its body. These appendages, sometimes called fins, appear to help the octopus coordinate its direction of movement, but their exact purpose is not fully understood. Because of these amazing "ears" of the octopus, Grimpoteuthys is called Dumbo the octopus - after the flying Disney elephant. It was first filmed by scientists on the research vessel Okeanos Explorer. “The expedition of the National Oceanic and Atmospheric Administration (NOAA), which took place in early 2014, proved that the scientific world does not know much about the inhabitants of the world’s oceans. “We still have a lot to discover,”– researcher Mike Vecchione, who took part in this expedition, said at a scientific conference.

This little guy was so cute that we all literally fell in love with him and gave him the nickname Dumbo! says Mr. Vecchione. “He has two rather unusual appendages on his head near his eyes that look very much like ears.” The cephalopod uses them like fins and moves very smoothly in the depths of the ocean, says the expert. - This cute sea animal cannot but evoke affection, or at least a smile - after all, this octopus really looks like a little elephant flapping its wings. While conducting research in the waters of the Gulf of Mexico, we never expected to find such a miracle of nature there,” the scientist admits. – To be honest, it’s breathtaking to think about how many miracles still await us!
IT IS IMPOSSIBLE TO OBSERVE DUMBO UNDER NATURAL CONDITIONS FOR UNDERSTANDABLE REASONS, therefore, not much is known about the animal’s habits. Most scientists agree that the octopus hovers above the very bottom in search of worms, crustaceans and mollusks, which constitute the main diet of grimpoteutis. Dumbo swallows the prey he catches whole, unlike other octopuses that live closer to the surface. His movements are a real dance. The deep-sea octopus Dumbo moves on jet propulsion, pumping water through itself, and the famous “ears”-fins serve as rudders-stabilizers. All this looks overall bright, impressive, noticeable and makes Dumbo stand out from the crowd of other octopuses. It seems to hover over the seabed in search of food and moves in a rather original way. He has special funnels on his body through which he shoots water. So it floats. At the same time, he diligently helps himself with his ears, flapping them like wings. By the way, Dumbo can use the jet engine and fins together or separately.
Maybe Dumbo would be more famous, but his hermit lifestyle prevents him from becoming famous. After all, it lives at extreme depths, and is also extremely rare. People learned about its existence only recently and have not yet studied it sufficiently. It should be noted that seeing this creature in the depths of the ocean is not so easy, because, despite the name of the elephant, the Dumbo octopus is not the size of an elephant. They say that it is half the size of a human palm.
The color of the animal can vary, like other octopuses, but Dumbo can also make his skin transparent, becoming almost invisible. Males and females of grimpoteuthis captured provide some insight into reproduction. Necropsies of several females showed that eggs were found in most of them. In all studied specimens, the eggs were at different stages of development, so oceanologists are inclined to believe that Dumbo breeds year-round, without a specific seasonal preference.
The difference between males and females is interesting: they have different patterns on the suckers of the tentacles and different sizes. Grimpos reproduce, like all eight-legged animals, by laying and incubating eggs, which are quite large in size. Usually the female incubates each of them separately. Due to the size of the eggs, the hatched octopuses are relatively large and sometimes look like adults.
Every time we succeed in making another discovery, we humans realize that there is still much we do not know and much remains to be discovered. There is no doubt that the depths of the sea still hold many secrets and the cute Gimpo is only a small part of this unknown world.
These cute deep-sea octopuses get their name from the “ears” that make them resemble the Disney character Dumbo the elephant. This genus includes 37 species, which differ in the size of their “ears,” color, and lifestyle.
One of the representatives was discovered at a dizzying depth of 7 km, making it the deepest-sea octopus to date. Dumbo octopuses are relatively small in size - only 20 cm. The largest representative discovered was 1.8 meters long and weighed just under 6 kg (this is closer to Dumbo the elephant :)). Unlike most other octopuses, they do not have an ink sac, which is used to release a cloud of ink to confuse predators. Probably, at such great depths, where it is dark, this method of defense did not justify itself.
Unusual “ears” play the role of fins, thanks to which these octopuses can move in any direction. Considering that they live at great depths, where there is not much food, then this skill turns out to be very important. Just look how elegant and graceful he is.
