Indo-Pacific Humpback Dolphin Sousa chinensis

The Indo-Pacific humpback dolphin is a warm-water dolphin that gets its name from the conspicuous hump beneath its dorsal fin. Generally seen alone or in pairs, the Indo-Pacific humpback dolphin shows a wide variation in color—some specimens are bluish gray, while others are almost white, particularly when they age. The Indo-Pacific humpback dolphin feeds on fish, octopus, and squid, and it rarely strays far from the shore. A similar species exists off the Atlantic coast of Africa, and both species roll their bodies when they breathe, instead of jumping clear of the water.
