What Is a Group of Dolphins Called?
Highly social, endlessly chatty, and never far from the rest of the pod.
A group of dolphins is called a pod, with herd used in older word lists and school reserved for very large gatherings that can number in the hundreds or thousands. Dolphins (family Delphinidae) rely on their pod for hunting, protection, and communication.
What Is a Group of Dolphins Called?
A group of dolphins is most commonly and accurately called a pod. Older word lists also cite herd, and very large gatherings, sometimes numbering in the hundreds or thousands, are called a school (or superpod). Dolphins are among the most highly social marine mammals, using signature whistles and echolocation to coordinate hunting, protection, and communication within the group.
How Big Is a Dolphin Pod?
A typical pod contains 2 to 30 dolphins, though membership can shift over time as individuals join or leave. Pods don’t have a single fixed leader — roles shift based on age, experience, and social bonds, with older, experienced females often playing key roles in guiding group behavior. In open ocean waters with abundant food, multiple pods sometimes merge into massive superpods of a thousand or more, which is when the term “school” comes into use.
Dolphin Facts
- Signature whistles: each dolphin develops a unique whistle that functions similarly to a name, used by other pod members to identify and call to that individual.
- Cooperative hunters: pods herd fish into tight balls that are easier for the group to feed on, and work together to defend against predators like sharks.
- Unihemispheric sleep: dolphins rest one brain hemisphere at a time, letting them keep swimming, breathing, and staying alert to predators while resting.
- Long lives: bottlenose dolphins often live 40–60 years in the wild, with females typically living longer than males.
- Built for speed: dolphins can reach sustained speeds of about 20–22 mph, with brief bursts even faster.
Example Sentences
- A pod of dolphins raced alongside the boat, leaping through the waves.
- Researchers tracked a school of dolphins stretched across the horizon during migration.
Other Names for a Group of Dolphins
Pod is the term most widely used and scientifically accurate for a dolphin social group. Herd is an older term still found on many collective-noun lists but used less often in modern marine biology. School is reserved specifically for very large gatherings, sometimes called superpods. Baby dolphins are called calves — there isn’t a distinct collective noun for a group of them specifically, since calves stay extremely close to their mothers rather than forming their own separate groups.

How do dolphins sleep?
Dolphins rest one brain hemisphere at a time, a state called unihemispheric sleep, which lets them keep swimming and stay alert while resting.
What’s the difference between dolphins and porpoises?
Dolphins generally have a longer snout, curved dorsal fin, and cone-shaped teeth, while porpoises tend to be smaller with a blunter face and spade-shaped teeth.
Are dolphins endangered?
Most dolphin species are not currently endangered, but several, including certain river dolphin species, are classified as endangered or critically endangered.
A Pod Built on Cooperation
A pod of dolphins is more than a swimming group — it’s a cooperative network built on communication, shared hunting strategies, and mutual protection.
