Tucuxi dolphin  (Sotalia fluviatilis)

Description

The tucuxi dolphin (pronounced ‘too-koo-shee’) quite closely resembles the bottlenose dolphin, but smaller. It is blue to light grey on the back, and fades to white or whitish-pink on the belly. There is a dark bar between the mouth and the flipper. The beak is slender and long, and the dorsal fin is triangular and slightly hooked at the tip (2). Both the beak and the dorsal fin may be tipped with white (5). Some marine populations have yellow-orange sides with a bright patch on the dorsal fin (5).
