A group of dolphins is called a pod. Pods can vary in size, from just a few dolphins to dozens, and they may consist of family groups or a mix of different ages and genders. Dolphins are highly social animals known for their intelligence, communication skills, and cooperative behaviors. Pods often work together to hunt for food, protect each other from predators, and engage in social interactions, such as playing and vocalizing. The dynamics of a pod can be complex, with established relationships and social hierarchies that influence their behaviors and interactions in the wild.
