American scientists have made many discoveries and nice photos of unusual sea creatures.
National oceanic and atmospheric administration released footage from the ocean’s depths with amazing animals.
American scientists are studying the nature reserves in the area of American Samoa in the Pacific ocean. Submersibles the scientists took many rare and unusual deep-sea animals.
Their appearance is so unusual that is reminiscent of aliens from other planets.
Корреспондент.net shows the most beautiful pictures of the new expedition and recalls the mission last year, which opened a large number of previously unknown creatures.
Prishelcy from space
Medusa of the cnidarian class Rhopalonematidae were found on the seamount UTU. This class of jellyfish there are channels that go vertically inside the “bell” of the jellyfish. Sometimes they have two sets of tentacles.
Biologists believe that the relaxation of the tentacles allows the jellyfish to eat optimally at a depth of about three kilometers.
The following video consists of cutting staff jellyfish fantastic forms and colors, which was discovered last year.
Fish from the squad hyperoartia (Chimaeriformes) belong to the class of cartilaginous fish, which are so named because their skeleton is made of cartilage, not bone. Chimeras are close relatives of sharks, they are evolutionary diverged about 400 million years ago.
Their diet consists of mollusks, crustaceans and small fish. On the sides of the Chimera there are lines which constitute mechanoreceptors, detektywa sound waves.
Point on the anterior part of the snout Chimera – electroreceptors that detect changes in electric fields – thus, the fish learns about the presence of living organisms.
Video – long-nosed Chimaera (Harriotta). She lives ten meters from the ocean floor. A family of long-nosed Chimera, as the name suggests, is characterized by a very long, elongated snout, which are nerve endings that help the fish to find prey.
At the end of the dorsal fin they have a poisonous spike that they use for protection. Garrity – the deep sea of chimeras, they are found at depths up to 2.6 km.
This rare organism belongs to the order of siphonophora. Each “flower” is actually a colony of animals that perform different functions.
To siphonophora also include, for example, a Portuguese ship, which, although it looks like a jellyfish, in fact, too, is a colony of many specialized individuals.
Actinoscyphia aurelia, which is shown in the video is at the top of dead coral. When she approaches the machine, it slams shut.
She eats just like a normal Venus flytrap, – folds located at the top of the disc in half and hit him digesting prey.
Like most anemones, this is a sedentary organism. She has no skeleton of reference the function of the intestinal cavity. Actinoscyphia aurelia feeds on small invertebrates, sometimes fish.
And this sea anemone is sitting on a rock at a depth of 1.5 kilometers.
Armored gurnard like walks on the seafloor using modified fins. These fish belong to the sea cocks, but malarvadi relatives differ four rows of bony plates along the body, each of which has a thick curved spike.
Also, the armored sea cocks are Horny projections on each side of the head and antennae are branched in its lower part. These antennae are the taste buds.
Oceanic octopuses of the genus Grimpoteuthis are known as the deep-sea members of the order of octopuses, they were met at a depth of seven kilometers.
In some species of Grimpoteuthis on the head there are two fin-like ears flying elephant Dumbo from the disney cartoon.
So they called octopuses or Dumbo eared. Flapping earlike appendages, the octopus rises in the water column.
Sea cucumbers or sea cucumbers belong to the echinoderms is of the same type, to which belong, for example, sea stars and sea urchins.
The sea cucumbers echinoderms characteristic of the dermal skeleton reduced, and the body was soft and leathery. Some species of sea cucumbers are edible, in this case they are called “trepang”.
Are usually “on the side” by lifting the front, the mouth end. Sea cucumbers feed on plankton and organic debris derived from silt and sand which passes through the alimentary canal. Other types of filter food with their tentacles, covered with sticky mucus, from bottom waters.
With strong irritation discarded through the anus posterior part of the intestine along with water, light, scaring off the attackers or distracting; lost bodies recover quickly.
The majority of known sea cucumbers have the grey and green shades, but the footage of American scientists exhibit a variety of colors.
Marine toads live at depths below 2.5 km. They have globular bodies and short tails. Covered with a large number of skin outgrowths or bony tubercles, spines or plates.
Plancii on the belly function as legs on which the fish is during the holidays. Scientists say the talent of the fish to the waiting prey.
At the end of the video there’s a moment after swimming with the fish displays its fins and sits on the stone.
Last year, scientists found a glowing purple ball diameter of five inches.
Biologists have suggested that they discovered a new species of tunicates, cnidarians or sea cucumbers. But they do not exclude that the balloon represents a previously unknown form of life, to identify where you will take a few years.
About other animals, too little was known, so we simply admire the wonders of nature.
