Generally, dolphins are found in pods for protection, support and social interaction. For many years, marine biologists have been studying how dolphins communicate and navigate through the ocean. Undoubtedly, they are intelligent creatures. In the past, they were also thought to be cute and friendly, but it has been discovered that some exhibit aggressive behavior. In the 1990s, the tide washed up nine young dolphins on the shores of Virginia, USA. After research, scientists concluded they were killed by larger dolphins. This discovery has already changed our ideas about dolphins and currently some people are wondering if swimming with them is really safe for humans.

In the 1990s, the tide washed up nine young dolphins on the shores of Virginia, USA. After research, scientists concluded they had been killed by larger dolphins. This discovery has already changed our ideas about dolphins, and currently, some people are wondering if swimming with them is really safe for humans.
