What Does “A School of Dolphins” Mean?
“School” is another cross-species borrowing, lifted from fish terminology, and it captures a real phenomenon: dolphins occasionally gathering in numbers well beyond a typical pod, close enough in scale and density to visually resemble a large school of fish. These large aggregations, often called “superpods” by researchers, form when multiple pods temporarily merge, usually around a major food source or during migration.
Superpods have been documented numbering in the hundreds to, in rare cases, over a thousand individuals, a striking sight and a genuinely useful survival strategy, since larger numbers can improve both foraging efficiency and protection from predators like sharks. These mega-gatherings tend to be temporary; once the resource driving them is exhausted or the migration leg completes, the group typically fragments back into its smaller, more stable core pods.
Example: “What looked from a distance like a school of dolphins turned out to be a massive superpod stretching almost to the horizon.”
