Pantropical Spotted Dolphin

Fascinating facts about the Pantropical Spotted Dolphin

• More than three million pantropical spotted dolphins still roam the oceans, but that's a sharp drop from the seven-million-strong world stock of the 1950s. Today, about two million of those individuals live in the eastern Pacific, the region once decimated by tuna nets. Between 1959 and 1972, just under five million dolphins were killed, with three million of those losses coming from the northeastern offshore unit alone. The stark decline shows how a single fishery can reshape an entire species' global numbers.
• Pantropical spotted dolphins don't reach breeding age until a decade or more after birth, females mature at 10-12 years and males at 12-14 years, depending on the offshore region. Gestation lasts just under a year, and mothers nurse for at least 1.5 years. In the wild they can live into their mid-40s.
• These dolphins are the acrobats of the sea, regularly launching splashy leaps that can clear the water for a second or more. They can sprint at 22-28 km/h, a speed comparable to a fast cyclist, and they travel in pods ranging from a few individuals to several thousand. Such social, high-energy behavior, even though they never actually eat the fish.
• Tuna-purse-seine fishing once wiped out three-quarters of the eastern Pacific's pantropical spotted dolphin population in just 25 years, but modern regulations have turned the tide. After the Inter-American Tropical Tuna Commission set mortality limits, deaths fell to just 373 in 2005, and U.S. vessels have cut by-catch by 95%. Yet the northeastern subpopulation still shows little sign of recovery, reminding us that preventing deaths is only the first step toward rebuilding numbers.
• A newborn pantropical spotted dolphin is only 80-90 cm long, but adults grow to about 2.5 m and weigh between 110 and 140 kg. Some individuals can tip the scales at 165 kg, showing a notable size range across the species.
