What Does “A Flock of Dolphins” Mean?
“Flock” is borrowed straight from bird terminology, and applying it to dolphins highlights something genuinely true about how they move: in tight, coordinated groups, changing direction almost simultaneously in a way that can look remarkably similar to a flock of birds wheeling in unison. Dolphins rely heavily on this kind of synchronized movement, both for efficient group travel and as part of coordinated hunting and predator-avoidance strategies.
Like “flock of bees” or other cross-species borrowings on this site, “flock of dolphins” isn’t the most commonly used term, “pod” holds that title, but it captures a real behavioral parallel rather than being a purely arbitrary linguistic transplant. Dolphins’ fast reflexes and constant echolocation-based awareness of their podmates’ positions make this kind of tight, synchronized group movement possible in the first place.
Example: “A flock of dolphins wheeled together just offshore, breaking the surface almost as one.”
