On occasion but often in schools or pods
Dolphins typically swim in groups known as pods, which can vary in size from just a few individuals to several dozen. These pods often consist of family members and can exhibit complex social structures. While the term "schools" is more commonly used for fish, it is sometimes applied to dolphins, but "pods" is the more accurate terminology for their social grouping.

schools cause groups of fish are always called schools
Humpback whales swim in pods primarily for social interaction, protection, and cooperative feeding. By traveling in groups, they can enhance their foraging efficiency, particularly when hunting for schools of fish or krill, using techniques like bubble net feeding. Additionally, being in pods provides safety in numbers against potential predators. Social bonds within pods also facilitate communication and mating opportunities.
Narwhals typically do not swim in schools like many fish do. Instead, they are often found in smaller groups or pods, usually consisting of a few individuals, especially during the summer months when they gather in Arctic waters. Their social structure is more fluid, and they may come together for feeding or mating but do not form large, organized schools.
Groups of fish are called a school of fish or a shoal of fish. example: The school of fish swam upstream.
they swim in schools
They swim in schools.Some have colors that help them blend in to their surroundings. Others change colors to match their surroundings. Some swim very fast to escape the danger. Some fish swim in very tight schools to confuse other fish. Some fish hide in the rocks and plants so the bigger fish cant get to them. Some fish can hide in poisonous anemonies and they are not affected by the poison but other fish are.
