A group of dolphins is commonly called a "pod." Pods of dolphins vary in size, often comprising just a few individuals or sometimes several dozen members. Social structures within these pods can be quite complex, as dolphins are known for their intelligence and cooperative behavior. They often engage in various activities such as hunting, playing, and communicating with each other using a range of vocalizations and body language. The strong social bonds within pods play a crucial role in their survival, as dolphins work together to navigate their environment, raise young, and protect each other from predators.
