Sturgeon Species has more than a dozen representatives. However, one of the most amazing fish is the ship. After all, if you believe the research scientists, that sea creatures came through the Union of other types. So, the gene pool of a thorn there are visible traces of sturgeon, Beluga and stellate sturgeon.

So let's delve into the wonderful world of nature and talk about what other secrets hides fish spike. Let's see how she looks, where it lives and what it eats. And also try to understand why it is today on the verge of extinction.

Fish spike: description

Adults can reach two meters in length. But most of the members of this species are much smaller. The body oblong, with pronounced, conical spines on the back. In fact, it is thanks to them that this fish got its name.

The Spike is markedly different from their closest relatives. For example, unlike other representatives of sturgeon, he has fringed antennae attached to the lower lip. This physiological feature spike received from their ancestors, who had common roots with the sterlet.

As for color, it ranges from light gray to greenish hue. But the belly of the fish is light, almost white color. In addition, the tongue is covered with star-shaped scales that are easily visible along the entire body.

Habitat

So, where does the spike? Fish feels equally well in both salt and fresh water. Therefore, its range extends for many kilometers, which is incredibly surprising many scientists.

So, representatives of this species can be found in the Caspian, Aral, Azov and Black sea and in the basins of those rivers that are adjacent to these water bodies. In particular, large populations of barbel live in the Ural, the Kura and Sefidrud.

fish spike description

Tongue-fish.

The way of Life of this fish begins in fresh water. Therefore, with the advent of spring, adults begin to migrate up the river in order to reach their spawning grounds. Here they spawn, then come back to the sea.

Soon from the eggs, the larvae hatch. It should be noted that the young are not in a hurry to leave their native water. A year goes by, and then they will go to salt water, along the way gaining strength for life in the open sea. Many spikes will long live in the mouth of the river so as to cross the last line for them is very difficult.

As for life cycle, the thorn-fish is a survivor. The average members of this species live about 20-22 years. However, in science there are cases where these fish live to be thirty years, which is a good indicator for the inhabitants of the underwater Kingdom.

Fish habits

Many believe the spike hulking fish, but it is not so. The truth is that this creature simply does not like to do superfluous motions, and because of this, prefers to lead a quiet lifestyle. However, this does not mean that the thorn is quiet and harmless. For example, hunting it reacts incredibly fast, not allowing the victim any chance to escape.

Red book

The Ship – a fish listed in the Red book of Russia. It just so happened that in the early twentieth century had allowed her catch that greatly reduced the population of this species. So, by 1980 its population has decreased by almost 80%, which worried scientists and conservationists. Therefore, in 1983, was issued a special decree, according to which the sheep were brought in the Red book. Alas, these measures are unable to correct the current situation.

Even today, the fish thorn is on the verge of extinction. Blame the fact that the spike reaches puberty only to the twelfth year of his life. And because of this, many individuals die much earlier than you can give birth to the first offspring.
