Typically, sharks are considered extremely dangerous animals, and call it being an ordinary fish is sometimes more than difficult. This is not surprising, because, just look at the size of that “fish” and the number of teeth in her mouth. Indeed, virtually all species of sharks are predatory animals. It is immediately noted that there are about 450 different species. However, there are sharks that are as food prefer small fish, plankton, who lives in the water, etc. in Other words, some sharks are natural purifying devices for water. As it turned out, sharks can live not only in seawater, i.e., salt, but also in fresh waters. However, this ability is given not to all representatives of this genus of animals. In this game we will talk about predatory sharks that feed on large species of aquatic creatures.
Moreover, sometimes they are not averse to eat people if they are nearby. The game shark is one fish mysteriously swam in the waters of the river called Thames. It flows through London which is the capital of great Britain. At this time you have to control the movements and actions of a Continue reading
The structure of the pharynx is also closely linked to feeding habits of fish. As indicated, the number and structure of Gill rakers may be very different — from a few small hard bumps predatory fish to a complex network of frequent rakers in silver carp — Hypophthalmichthys molitrix (Val.), litumelo planktonic algae. The mullets — Mugili – dae — muscular throat adapted for crushing lisovogo clump, consisting of detritus and vegetation. Some fish developed teeth on the pharyngeal bones. Some they are on top – and ninepatch bones, as, for example, wrasses — Labridae, or only ninepatch, as, for example, cyprinids — Cyprinidae.
Haeckel (1843) divides nizhnelomovskie teeth of cyprinid by the nature of the structure related to their function into four types:
1) hollowed — excavati, a type of Longhorn beetle,
2) chewing — mastic torii, a type of carp, Continue reading
Fishing giant fish — fishing threat. Huge swamp of matter, speed devil hulks, giant predators of the deep — the most interesting specimens to study science, people and just the extreme. In the depths you can find a huge, strong and even prehistoric predators. You can find such representatives, which are not known to the slightest fact. A real opportunity to explore predatory fish is available to us through the aquarium. Surprising is the fact that they are huge in size, each time increases more and more.
The most dangerous and worst are dangerous and a threat to the entire underwater world. But most often such giants as fish — Marlin the most desirable prey for any athlete angler. Catching Marlin and try to get him out, the fish starts to jump, as a result, she spends almost all its energy. Taking advantage of this moment, the fishers set on the fish label. Tags similar GPS Navigator: provides complete information on location of fish, water temperature, depth. Such labels help scientists obtain information about the depths of the seabed, biological balance, life and survival of fish. Continue reading
