A LITTLE WILDLIFE PERSPECTIVE

How big is a bottlenose dolphin?

Compare your height to a bottlenose dolphin.

Common bottlenose dolphins measure roughly 1.8–4 m (6–13 ft) long. The comparison uses a 3 m adult in a horizontal swimming pose.

GET TO KNOW THE ANIMAL

Small facts. Big discoveries.

Common bottlenose dolphin · Tursiops truncatus

A curved dorsal fin and a short beak give the bottlenose dolphin its familiar outline. It uses sound to communicate and to locate prey underwater.

Bottlenose dolphins can hunt alone or cooperate to herd fish into a tight group. Their social groups may split apart and re-form as they travel through coastal or offshore waters.

  • They grip fish with their teeth and usually swallow them whole.
  • Calves can swim close beside their mothers while nursing.

How big do adults get?

Male
Shared species range: about 1.8–4 m long
Female
Shared species range: about 1.8–4 m long

These are species-wide lengths, not sex-specific averages. The drawing is scaled from the beak to the tail; the ruler includes the dorsal fin and flippers.

Height, length, or weight?

Standing height runs from the ground to the top of the animal. Shoulder height stops at the top of the shoulders. Length runs along the body; it is not how tall an animal stands. Weight tells us how heavy it is.
