What is a dolphins main predator?
Predators. Natural predators include certain large shark species such as tiger sharks (Galeocerdo cuvier), dusky sharks (Carcharhinus obscurus), bull sharks (Carcharhinus leucas), and great white sharks (Carcharhinus carcharias). In Sarasota Bay, Florida, about 31% of dolphins have shark bite scars.
How do dolphins get their prey?
To get their food, they usually hunt in a group through different techniques. One of them is a kind of “sheep-herding”, in which a group of dolphins circles a group of fish to get them together in one place while others start eating them in turns. That way, every dolphin gets to eat efficiently.
Do dolphins circle their prey?
Most commonly, dolphins work together to herd or corral their prey. Some cetacean pods round up fish into “bait balls” and take turns plowing through the fish cluster, snatching their disoriented prey.

How do Dolphins defend themselves against predators?
When faced by a predator, dolphins often circle, head butt or use their tails to hit the other animal in self defense. According to the Sarasota Dolphin Research Program, sharks often attack dolphins from behind or below as shown by bite scars. Sometimes, dolphins and sharks swim in nearby water without interacting.
Why do humans kill dolphins?
Sometimes, humans kill dolphins not because they are a source of food, but because they prey on the same fish species than humans. Therefore, many fishers have killed dolphins only because they are a competition for the fish. In some countries, people eat cetaceans, including dolphins.
What is the function of the Dolphin?
Function. Dolphins find food with their sense of sight and more importantly, with their sense of hearing. Dolphins can emit sound waves that return an echo vibration from their prey, an ability called echolocation. Echolocation provides information such as the object’s size, shape, speed and which direction it is going.
