No, the saltwater itself does not make pink dolphins turn pink. The coloration of pink dolphins, particularly the Amazon river dolphin, is primarily due to their genetic makeup and the presence of blood vessels near the surface of their skin, which can appear more pronounced in warmer temperatures. Their coloration can also change based on factors such as mood, temperature, and environmental conditions.
