Do sharks eat dolphins? 

In this article, we are going to answer: do sharks eat dolphins, what is a shark, what are dolphins, are sharks afraid of dolphins, and who wins a fight between a shark or a dolphin. 

Do sharks eat dolphins?

Yes, sharks do eat dolphins but not all species of sharks eat dolphins. Dolphins are not the main source of food for sharks but sharks and dolphins have always been enemies and sharks will win a fight against dolphins. The main source of food for sharks includes

  • Fish
  • Seals
  • Turtles
  • Crustaceans 

Sharks can identify a weak dolphin from a pod and attack those who will lose the fight. The most dangerous sharks for dolphins are the tiger shark and the white shark. 

What is a shark?

Sharks are fish that can measure about 7 inches to 32 feet and can weigh from 1 ounce to 20 tons. The largest shark is the whale shark, considered the largest species on earth because it can grow up to 55 feet.

Sharks live in the ocean except for the bull shark and river shark which can also be found in freshwater. 

Sharks are expert predators with multiple rows of teeth that give them a power bite to kill almost whatever they can. Some species of sharks are solitary while others travel in a group such as the lemon shark. 

The most common food for sharks is by eating other animals such as sea lions, seals, and other marine mammals. Humans are not part of the shark menu but they can attack humans out of curiosity or defense. The probability of dying from a shark attack is almost null. 

Some sharks that are on top of the food chain include

  • Tiger shark
  • Blue shark
  • Great white shark
  • Mako shark
  • Tresher shark 
  • Hammerhead shark 

What are dolphins?

Dolphin or Odontoceti measures up to 32 feet and can weigh up to 6 tons. There are about 36 species found on seawaters and a few oceans can live in freshwater. The largest dolphin is the orca which can measure up to 30 feet long. 

Dolphins travel in groups, known as school or pods, and have a special characteristic in which they can communicate with squeaks, whistles, and clicks. 

Male dolphins are known as bulls while female dolphins are called cows and young dolphins are called calves. Dolphins have commonly hunted in Japan apart from being used to being kept in captivity. 

Are sharks afraid of dolphins?

No, sharks are not afraid of dolphins but they think before they attack a pod or a group of dolphins. Dolphins usually travel in large pods or groups and they can win easily this way. Sharks look for the weaker dolphin in the group or solitary dolphins so they can attack. 

So it is not that sharks are afraid of dolphins, they just prepare for the attack and if they believe they won’t win, they prefer not to attack. 

Who wins a fight, a shark or a dolphin?

According to several sources, sharks win the fight because of their bodies and jaws. Sharks are natural carnivores while dolphins are not. Also, dolphins are commonly seen in groups and when they are attacked alone, they will probably lose because sharks are lonely animals.

Sharks are faster and have a more predator activity towards dolphins. Even if dolphins are the smarter animals second to humans, they do not have the physical ability to fight and attack sharks as sharks do against dolphins. 

Specifically, dolphins will lose within seconds against a white shark. Follow this link for a video between a dolphin and a shark.
