What species of shark is in the aquarium and why don t they attack people?

The sharks in the aquarium are just ordinary sharks, and they don't attack people because they have been domesticated by their keepers.

The sharks in the aquarium are all more docile species, usually lemon sharks, blackfin and other less aggressive sharks, and their trainers know their food intake very well, and if the food intake is properly controlled, humans will generally not be harmed.

The species is the same as in the sea, because if you are full in the aquarium and there is no smell of blood in the aquarium, you will not attract sharks.

1. Great white shark: The great white shark is relatively large. They are very aggressive and have teeth that are about 10 centimeters long. Their tails are crescent-shaped and more distinctive.

2. Red-tailed sharks: The origin of this shark is in Thailand, although their size is not particularly large, but their personality is more irritable, and they have a strong sense of territory.

3. Steller shark: Steller shark is an ornamental shark species, and they can be bred in fish tanks. Their body length in adulthood is 30-40 cm, and they are still relatively small.

Their feeding habits are relatively mixed, and they do not have too high requirements for oxygen content in the water, and their adaptability is relatively good.

4. Whale shark: It is the largest shark species and the largest fish in the world. In adulthood, they can even reach a body length of 20 meters.

Key Value:

1. Shark watching.

Some large aquariums and aquariums at home and abroad have specially opened shark aquariums to raise more than 10 kinds of sharks with temperate character training and ornamental value, such as striped bamboo shark (also known as spotted bamboo dog twisting), leopard shark (also known as big-tailed tiger stripes), etc., and the keepers dive into the pool (box) to feed the shark or dance with the shark to show the mysterious shark world to visitors.

2. Maintainer of marine ecological balance.

Sharks are almost exclusively carnivorous species, with only a few species such as whale sharks and basking sharks feeding on plankton. Carnivorous sharks have a strong bite due to their strong contractile muscles and sharp teeth, and can eat molluscs, crustaceans, large fish and marine mammals, and even attack small boats and eat people. In the marine ecosystem, sharks are the uppermost part of the biological chain and play an important role in maintaining ecological balance.

3. Provide materials for industry.

Sharks have well-developed livers with 2-3 lobes, and their weight accounts for 15%-20% of their total body weight. The oil content in the liver is as high as 63%, and this oil does not freeze at -50, making it a high-grade lubricant. In addition, shark skin is processed to make high-quality leather.

Sharks are fish.

Sharks are fish, a type of fish of the phylum Vertebrates, the class Chontilagina, that live in the ocean, are fish in the ocean, breathe with gills and swim in the water with fins. The body of the shark is long spindle-shaped, the pectoral fins are normal, there are gills on both sides of the head, and most sharks have hard, dark gray teeth, and many shark tooth patterns.

Sharks reproduce mainly through three methods: oviparous, ovoviviparous, and viviparous. When the body length increases to a certain length, the rate of growth begins to slow down, while the weight gains rapidly. Data show that freshwater sharks generally grow at an average rate of more than 15 grams per day during the suitable growth time between June and January.

Freshwater sharks that have been raised for 2 years can grow to more than 2 kilograms.
