  "description": "Bottlenose dolphins are the most common and well-known members of the family Delphinidae, the family of oceanic dolphins. Bottlenose dolphins live in groups typically of 10-30 members, called pods, but group size varies from single individuals up to more than 1,000. Their diet consists mainly of forage fish. Dolphins often work as a team to harvest fish schools, but they also hunt individually. Dolphins search for prey primarily using echolocation, which is similar to sonar. \n\nchild friendly persona\n\nPersonas by LisaAtTheBeach"
