The northern right whale dolphin is a small, slender marine mammal found in the cold, temperate North Pacific Ocean. These animals are known for their sleek, all-black bodies that lack a dorsal fin, often showing a white patch on their belly.

Growing about 6.6 to 9.8 feet long, they have a short beak, small flippers, and 80 to 95 thin teeth for eating fish and squid. Females are slight smaller than the males, and young dolphins gain their dark color within a year.

Northern right whale dolphins are very fast swimmers. Their average swimming speed is around 16 miles per hour. They can reach top speeds of up to 25 miles per hour.

When traveling fast, a group looks like they are bouncing along the water. They make low, graceful leaps together. They can travel as far as 23 feet in one single leap.

These dolphins dive up to 660 feet deep to search for food. They hunt for squid and fish, especially lanternfish. They also feed on other ocean prey like Pacific hake and saury.

Pair the northern right whale dolphin with the short-beaked common dolphin skull replica to compare standard ocean snouts. The rough-toothed dolphin female skull replica works well to show unique tooth ridges. The Risso’s gray dolphin skull replica provides a massive contrast with its blunt, rounded head shape.
