This material describes an interesting fish that do not occur in our country. For assistance in the preparation of the material the website "Your child would like to thank the Maritime Aquarium at Chistye Prudy.
Although this fish belongs to the family of the most good-natured, to stroke her on the back is not recommended, because it is often full of poisonous thorns . The fish-crocodile stretched-prelusory body shape, much like the toothy alligator. As fish poison, ichthyologists and could not establish whether the "underwater" crocodile toxic spikes and fins.
Fish-crocodiles - a rather large creature. They can grow up to one meter in length! These marine animals are enviable composure, perhaps realizing the advantages of its crocodile appearance, and meeting people, not frightened. Fish are sedentary lifestyle, preferring all day to lie on the belly, buried in the sand, waiting for unsuspecting prey.
To meet these cuties on the coral reefs off the coast of South-East Asia, Australia, Indian ocean and Red sea. And since they live on a relatively small depth, they can get even a novice diver.
Flying fish rarely grow larger, because they are important speed and maneuverability. The greatest representatives of this species can reach 50cm in length, but most stops at around 10-15 see the Most important characteristic feature of the flying fish - a huge pectoral fins, commensurate with the length of the body. Beautiful coloring flying fish charms: dark blue back, silver sides and belly and pectoral fins are iridescent: they can be plain - transparent, blue or green, and can variegated with bright stripes or spots.
A unique feature of the flying fish is their ability to fly, which developed as a way to escape from predators. Developing in the water a considerable speed (about 60 - 65 km/h!), this fish jumps out on the sea surface and some "flies" with the expanded pectoral fins, vigorously increasing speed, "dangling in the water" long lower lobe of the caudal fin. Then the fish comes off the water and opening the abdominal fins plans over its surface. In some cases, Pappus when flying slightly touches the water the lower lobe of the caudal fin and vibrating them receives additional acceleration. In history there were cases when flying fish lasted more than 30 seconds, and the distance was 200, and even 400 meters! The average altitude of these fish - 1-2 PM
Flying fish are usually kept in small flocks, usually up to a dozen individuals. These groups consist of similar sizes of fish, belonging to the same species. Small flocks often in large shoals, and in the feeding areas you can sometimes stumble upon significant accumulations of flying fish, consisting of many schools.
Menu flying fish not very diverse: they mainly feed on planktonic animals that live in the surface layer, small crustaceans and pteropod molluscs, and fish larvae.
In the sea there are many animals, like plants. In most cases, it invertebrates. But there are also fish, which could not be distinguished from the grass! The ichthyologists even have a special term for the accumulation of the same fish - eel garden. Inhabit such gardens fish belonging to the family of marine eels.
On average, the length of living in the Red sea garden eel reaches about 80 cm, it is almost waist-man! These lazy fish is almost not swim. Instead, they "drill" tail in the sand vertical burrow, climb where approximately one third, and the head and torso upright stick in the water against the current. At the slightest danger eel hiding in a hole entirely. Therefore, the tail of these creatures are very strong, because to quickly die, need great power! In the skin of acne, there is a special mucous cells secret which binds the sand walls of the holes, and does not allow them to flake off.
Often such strange marine life can be found on the sandy bottom and the slopes of the red sea, where there is a gentle current. Colonies of lazy-acne sometimes reach several hundred individuals! However, the similarity of the plants plays acne on hand - masquerading as innocent weed, they suddenly attacked the passing of small fish and plankton, not waiting for a trick on the side shoots.
