Peale's Dolphin
Lagenorhynchus australis · also called Peale's porpoise
Riding the bow waves of boats navigating the channels near Cape Horn, a Peale’s dolphin combines speed and agility along some of the roughest coastlines in the Southern Hemisphere, rarely straying far from the rocky shores of southern South America.
Overview
Peale’s dolphin, Lagenorhynchus australis, is a Least Concern marine mammal native to coastal and ocean habitat across the southeastern Pacific and southwestern Atlantic around southern South America. Its fast, agile swimming, distinctive grey-and-white markings, and close association with the rugged channels near Cape Horn make it one of the more visually recognisable and behaviourally engaging small dolphins found anywhere in the region.
A coastal specialist built for rough water
Thriving in the narrow, often turbulent channels near the southern tip of South America, Peale’s dolphin has adapted to a coastline that challenges many other marine mammals, using speed and agility to navigate waters where currents and weather can change quickly.
Status
Least Concern, remaining widespread and generally stable across suitable coastal habitat around southern South America.
