Minoga (lat. Petromyzon Linnaeus) is the largest biseless from the detachment of mineshaped. Belongs to the genus of sea lamps (lat. Petromyzon).
The body has many muscles, rather thick. The plates on the upper jaw are small, there are two teeth on it, which are in contact with their bases. The funnel in the mouth has several rows of teeth, and on the lower jaw there are about ten. There are many labial teeth that are located radical rows. Teeth have strong enamel, pointed. There is a pair of fins on your back, which are separated by a small interval. The dorsal fins are quite smooth into the tail.
Young people have a monotonous gray color, and when the adult is reached, their color changes to olive, there are many spots of dark and light shades on the body. Coloring varies depending on the color of the soil, near which lampreys live. The sides and back of adults are clearly covered with prominent spots.
The length of the body reaches eighty centimeters, in rare cases, these fish can grow up to a meter in length. Body weight of about two kilograms.
The main habitat is considered the North Atlantic. They can be found in Europe, but in those parts they do not particularly spread due to specific climate requirements. Lives at a small depth, basically it varies from two to four meters.
Lifestyle and reproduction
The beginning of departure on the spawn begins in June, the first thing the male builds a nest at a short depth, pebble soil is usually selected as a place of construction. The nest is a tunnel with a depth of about 50 centimeters. For fish, this is a rather complicated task, it spins in place, raising the sand with the help of the mouth. The male is trying to protect the building with all his might until the female comes there. The female individual is attached to the stone, which is located near the entrance to the tunnel, and the male is sucked up to it from the side, after which he turns around it, moves down and frees it from caviar, immediately fertilizing them.
According to scientists, the sea lamp is spawning only once in his life. This usually happens between spring and summer. The larvae of this species are called sandrocks, they are born two weeks after the end of the spawning ground, after which they are in the nest for about a week, subsequently settling with the help of the current. After some time, when the larva finds a habitat, it burns in the ground at the bottom of the reservoir. There they spend about six years of their lives, and later leave the ground, going into free swimming. So the second stage begins in the lapels, which is called sea. Young animals rolls along the river into the sea, looking for fish and tries to clash to it. As victims for parasitization, they usually choose cod, flounder or herring. Often, the consequences of such a “neighborhood” are the death of a fish on which a lamprea parasitizes.
Even considering the fact that a lampage is a rather large predatory fish, she has many enemies to whom she cannot oppose anything. This species often becomes food for large crustaceans and fish, and the larvae of sea laines are often used in the diet of many water inhabitants.
In addition to marine residents, birds are hunting for representatives of this species. Often storks and herons who catch their prey in shallow water can get lamps from silt without any problems in which they live. In addition, there are some diving bird species, for example, cormorants, which can also simply catch and eat fish.
At the bottom of water pools lives the main enemy of the lapre burbot, which is considered one of the most dangerous sea fish living at the bottom of the reservoirs. In the winter, the Minoga can eat a beluga that rarely hunts for such a trifle, but still does not disdain it and eat it for food.
Population and status of the species
The view of the lampreys is very numerous, their individuals can be found anywhere in the oceans. Fast reaction, fertility, accelerated migration all this allows you to survive the individuals of this species in any natural conditions, provided that there is good soil around them and the water temperature is not particularly hot.
Several countries are engaged in mass capture of the damper: Finland, Russia, Latvia and several more countries. Although these individuals are not particularly distinguished by external data, their taste and nutritional value are actually comparable to red fish. In the seas of the Baltic, about three hundred tons of a lamprea are caught, which subsequently marinating and canned.
- Plowers are considered one of the most ancient animals that have survived to this day. Without special external changes, they exist in the world about four hundred million years ago.
- The teeth that are endowed with individuals of this species, very sharp and without any problems pierce even the strongest skin. They hid a liquid that is something similar to the gastric juice. They inject her into the body of the victim, thereby poisoning her.
- These fish have no stomach, so food is processed in the body of their victims. They make gruel from the blood and meat of the animal, and then eat it with their tongue.
