The intensity of the pink is generally linked to blood vessel dilation and is often more vibrant in males, leading researchers to believe it plays a role in social signaling and mate selection. This adaptation is so refined that it allows them to hunt effectively during the night and in water with visibility of only a few inches.

While most dolphins possess fused neck bones that restrict head movement, the boto has unfused vertebrae, allowing it to turn its head up to 90 degrees. Echolocation in Turbid Waters Vision is often unreliable in the heavily sedimented, tea-colored waters of the Amazon basin.
Furthermore, their bulbous forehead, known as the melon, is highly developed and acts as an acoustic lens, focusing the sound waves they emit for echolocation with exceptional precision. They also exhibit a unique hunting technique known as "kerplunking," where they slap their flukes on the water surface to stun fish or scare them out of hiding, demonstrating a high level of problem-solving intelligence.

This crucial feature enables the dolphin to weave effortlessly through submerged tree trunks, dense vegetation, and intricate root systems that form underwater corridors in the Rio Negro and other tributaries. Unlike the rigid dorsal fins of oceanic dolphins, the boto’s dorsal fin is reduced to a low ridge or even a mere ridge of connective tissue.
