Description
Size: 2.6 m

Weight: 200 kg

Color: The body is bluish-grey on the back and the belly is white or pink. A dark grey strip runs from the eyes, along the flanks. This stripe gives the face the effect of a mask. Creamy-white borders above and below the stripe enhance the bold effect. The pattern of stripe becomes more marked with age, something which holds true with many other dolphin species.The upper lip, flippers, fin and flukes are dark.

Fraser’s Dolphins have robust bodies, with short but well-defined beaks. The flippers are relatively small and pointed. The trailing edge of the tail flukes is concave, and the dorsal fin is small, pointed and slightly sickle-shaped. There are 34-44 pairs of slender pointed teeth in each jaw. The total number of teeth is at least 160, going up to 172.

The swimming style of the species has been described as aggressive, with the spray created as the animal surfaces to breathe. The dolphin may be found in the company of other cetaceans, including Spotted Dolphins Stenella attenuata and Sperm Whales Physeter macrocephalus.
