There are many kinds of sharks and dolphins. Although they are both carnivores, the types of prey they hunt are different. Dolphins generally eat fish that are much smaller than them, while sharks can hunt animals that are slightly larger, such as seals and sea lions, and there are records of hunting dolphins. So in this way, sharks are not afraid of dolphins. But there's always an exception, and the larger species of Dolphin, the killer whale, also has sharks on its menu.
1. Intelligence: As we all know, the dolphin is a very intelligent animal. It is said that the intelligence of an adult is equivalent to that of a child of 6-7 years old. The brain accounts for about 1.17% of the body's proportion. But sharks are not ordinary people, such as Lu's hammerhead shark brain specific gravity of up to 1.2%, so it is difficult to compete from the pure intelligence.
2. Sociality: Dolphins are social animals. They usually form a group of more than 10 dolphins. In places with abundant food, they may even form a super group of hundreds of dolphins. They gather together not simply as a hobby, but as a division of labor and cooperation to hunt for food. Sharks are much more solitary. Most live alone, and only Carcharhinidae can hunt together.
3, predation skills: Shark predation means is very strong, thanks to their streamlined body, and their teeth can be constantly regenerated, the sense of smell is also very keen. It usually approaches the prey slowly and kills it by sneak attack. Dolphins, on the other hand, rely on their unique sonar system, they can lock prey, and gradually close to form a siege. After that, it will continue to narrow the scope and control the fish. Others will begin to breach the defenses of the fish, breaking their ranks, and they will rotate around and eat to ensure that everyone in the group can eat.
So to sum up, sharks and dolphins which powerful and can not be generalized, but also according to the species and number of both sides to judge.
