Of the family of gray sharks, the blunt-nosed is the most famous. It has several names: bull shark and gray bull shark. For what it is called so, you will learn a little later. This subspecies is found almost all over the planet. Where the waters are warm and shallow, there will definitely be a blunt-nosed shark. It can be found in the Amazon, on the Ganges, Mississippi, as well as any others that flow into the ocean. For people, this shark is very dangerous, because it is one of the three most cruel man-eating sharks.
Where does it live?
It is noteworthy that quite often the bull shark enters the rivers. which is not typical of other species. She also goes very far upstream, but in most cases does not fall to a depth of more than 30 meters. If we talk about the Atlantic Ocean, then it can be found off the coast of southern Brazil, the USA, Morocco and Angola. The original home of this predator is the Indian Ocean. Here the blunt-nosed shark is almost everywhere. It can be seen from the coastal zone of Africa and all the way to Kenya. Visited the bull shark and the Pacific Ocean. Here it can be found in almost all the islands. These sharks are not found only along the south side of Australia. A dangerous predator feels great in the muddy waters of the Amazon, it is very common on the riverGanges. The bull shark loves warm currents and tends to avoid temperate latitudes.
Predator Appearance
The body of the bull shark is stocky, for this simple reason people call it "bull". This corresponds to the aggressiveness of this representative of gray sharks. Males are slightly smaller than females. The length in most cases is no more than 2.5 meters, and the weight is about 130 kg. At one time there was talk that the fishermen managed to catch a female 4 meters long, but there is no evidence of this. It is noteworthy that the blunt-nosed shark, according to researchers, can weigh more than 315 kilograms. The number of dorsal fins is 2. Moreover, the first is slightly larger and higher than the second. The caudal fin is remarkable in that it is an order of magnitude longer than that of other members of the gray shark family, and it is also located slightly lower. The jaws of the predator are compressed very strongly. The bull shark becomes very dangerous also because it is quite difficult to spot. This is due to the gray back, which is completely invisible, especially in muddy water. The belly of the shark is white.
On nutrition and behavior
This predator is of great interest to researchers because of its unpredictable behavior. In the water, it is impossible to predict the actions of a shark. She can either attack a person or not. The same applies to large animals that are nearby. Apparently, a lot depends on whether she is hungry or not. Today, the bull shark is put in the same place with the white and tiger sharks in terms of danger. Usually hunts.representative of this species exclusively alone. It is very rare to see a pair of predators foraging for food. Cases of pack hunting have not been found at all. This may be due to exceptional aggression during foraging, directed even at weaker relatives, which predators later eat. However, the bull shark is extremely lazy and will not chase food once again, especially if it is full. The diet consists of fry of sharks, fish and even dolphins. Although the latter are rarely attacked, because there is a chance of being defeated. This is due to the fact that dolphins rarely swim alone, and in a flock they can easily kill a predator.
What is interesting about the blunt shark
It is noteworthy that this species of fish is a territorial animal, this applies to males. For a potential enemy, they can take anyone who swims into their territory. It was not uncommon for people to become victims of a bull shark just because they swam too far or dived too deep. By the way, researchers are now talking about a high level of testosterone in the blood of this predator. Apparently, this is due to the excessive aggressiveness of the individual. Today we can say that there are far fewer recorded attacks of a blunt shark on a person than unofficial ones. This is due to several factors: firstly, it is sometimes extremely difficult to understand whether it was really a bull shark or some other species, and secondly, in third world countries, in most cases, they do not attach importance to the attacks of these predators, since there it is notrare.
The blunt shark is a danger to humans
It's safe to say that sharks should generally be avoided, regardless of species or size. As for the blunt-nosed sharks, they should be feared the most. In particular, due to the fact that they are very unpredictable and extremely aggressive against a person or any other creature. However, there are practically no cases of this predator attacking a group of people or marine animals. So if you do swim, don't do it alone. Another important point is that the blunt-nosed shark feeds at dawn and dusk. It is not recommended to swim too far or even go into the water if there may be a predator in it, as there is a risk of becoming its prey. And in general, swimming on the beach or in the river, where this cannibal is supposed to be, is definitely not worth it. Moreover, this representative can be in both s alt and fresh water, the main thing is that it be warm. It always makes sense to swim as close to the shore as possible. Often the gray bull shark, or blunt-nosed shark, does not swim too close to shallow water.
Conclusion
So we looked at what kind of predator this is - a blunt shark. The danger to a person is extremely great, especially if she is in a bad mood or she is hungry. Sometimes these predators are not averse to tasting the fry of other sharks of their own kind. By the way, it is worth noting that the blunt-nosed shark is a viviparous fish. This means that femalesgive birth to babies. The length of the babies on the first day is no more than 60 centimeters. Individuals reach sexual maturity with a body length of 1.5 to 2.5 meters. The number of fry born can vary greatly, so there can be either 3-4 or 10-12 pieces. They hatch for more than 10 months. After about 10 years of life, the animal reaches its maximum size. To date, the bull shark is an object of poaching, as its meat is highly valued.
