Sleek, smartly marked and tirelessly playful, the Pacific white-sided dolphin can be easy to identify. That’s because it throws itself out of the water so often that it leaves little doubt about its identity. The body is black on the back, with striking light gray flanks and a pearl-white belly. Two gray stripes run along the entire length of the back. These markings, which some people liken to suspenders, are easily seen from above when the dolphin is riding bow waves. The dolphin has a short snout, or beak, and long curved pectoral flippers. Its black and grey dorsal fin is tall and curved. When fully grown, the Pacific white-sided dolphin is about 2.5 metres long and weighs up to 180 kilograms.
