Silver scales flash in unison through turquoise currents, a swirling mass of fins slicing water like living blades. Gills flare rhythmically, drawing oxygen from the depths, while bodies undulate in precise harmony—thousands strong, from tiny guppies darting to sharks gliding at the edge. They weave through coral labyrinths, devouring algae and insects, their collective pulse a vital thread in the ocean's endless chain.
Schools of fish are large groups that swim together for protection, feeding, and migration. Thriving in aquatic ecosystems, they use gills for oxygen and span thousands of species, from guppies to sharks. They regulate algae and insects, forming key food chains, and provide protein, omega-3s, and vitamins for human health.
