inhabited?
noteworthy that often comes a bull shark in the river.What is unusual for other species.She comes very far upstream, but in most cases does not go deeper than 30 meters.If we talk about the Atlantic Ocean, it can be found off the coast of southern Brazil, the US, Morocco and Angola.The original home of this predator is considered to be the Indian Ocean.Here roundnose sharks are almost everywhere.It can be seen from the coastal areas of Africa and up to the Kenya.I visited the bull shark and the Pacific Ocean.Here you can find almost all the islands around.None of these sharks only along the south side of Australia.Dangerous predator great feeling in the muddy waters of the Amazon, is very common on the river Ganges.Bull shark loves warm currents and tries to avoid latitude temperate climates.
Appearance predator
Body stocky bull sharks, for this simple reason people call it "bull."This corresponds to the aggressiveness of the representative gray sharks.Males are slightly smaller than females.Length in most cases is no more than 2.5 meters, and weight - 130 kg.At one time, there was talk that the fishermen managed to catch female 4 meters long, but there is no evidence for this.It is noteworthy that the bull shark, according to researchers, can weigh more than 315 kilograms.The number of dorsal fins - 2. And the first few larger and higher than the second.The caudal fin is remarkable in that it is an order of magnitude longer than that of other representatives of the family of gray sharks, as it is situated just below.The jaws of the predator are compressed very strongly.Bull shark becomes very dangerous also because it is difficult to notice.This is due to gray back, which is quite evident, especially in the troubled waters.The belly is white shark.
about nutrition and behavior
Researchers great interest is the predator because of his erratic behavior.In water, it is impossible to predict the actions of sharks.It can attack both human and no.The same applies to large animals caught nearby.Apparently, a lot depends on how hungry or not.Today, the bull shark-tied for a place with white and tiger sharks in the degree of danger.As a rule, preys representative of this type entirely alone.Very rarely can be seen foraging pair predators.Cases gregarious hunting were found at all.This may be due to exceptional aggression during foraging directed even weaker relatives, which predators and eat later.However, the bull shark is extremely lazy and once again for the food not pursue, especially if it is full.The diet consists of juvenile sharks, fish and even dolphins.Although attacks seldom last, because it is likely to be defeated.This is due to the fact that dolphins are rarely swim alone, and without a bunch of problems can kill the predator.
What is interesting bull shark
is noteworthy that this type of fish is a territorial animal, it concerns males.For a potential enemy, they can take anyone zaplyvet their territory.Often, people are becoming victims of a bull shark just because of the fact that swam too far or dive too deep.By the way, now researchers say the high level of testosterone in the blood of the predator.Apparently, this is due to overly aggressive individuals.Today we can say that the bull shark attacks reported per person is much less than the informal.This is due to several factors: first, sometimes very difficult to figure out whether it was really a bull shark or any other kind, and secondly, in third world countries, in most cases, do not attach importance to attacks of predators, as there isare not uncommon.
bull shark - a danger to human
can say with great certainty that all sharks must be avoided, regardless of the type and size.As for the bull shark, they should fear most.In particular due to the fact that they are very unpredictable and extremely aggressively opposed to any other person or entity.However, virtually no cases of predator attacks a group of people or marine animals.Therefore, if and swim, do not do it alone.Another important point - the shark eats roundnose at dawn and dusk.It is not recommended to swim too far away or even go into the water if it can be a predator, as there is the risk of becoming his prey.And indeed, on the beach or swim in the river, which is alleged to be the ogre, just not worth it.Especially that the representative can be, both in salt and fresh water, as long as it was warm.It always makes sense to swim as close as possible to the shore.Often gray bull or bull shark, do not swim too close to shallow water.
Conclusion
So we looked at what kind of a predator - bull shark.The risk to humans it is extremely high, especially if she has a bad mood or she is hungry.Sometimes these predators are willing to taste and fry of other sharks of their own kind.Incidentally, it is worth noting that the shark is viviparous roundnose fish.This means that the females give birth to fry.Length toddlers on the first day does not exceed 60 centimeters.Puberty reach individuals with a body length of 1.5 to 2.5 meters.The number of juveniles being born can be very different, so they can be either 3-4 or 10-12 pieces.They hatched more than 10 months.After about 10 years of life the animal reaches its maximum size.Today is the bull shark poachers target species, since its meat is very valued.
