The amazon river dolphins or botos are born grey and become pinker with age They have a long powerful
beak, small eyes and are slow swimmers. When excited, dolphins will flush to a
bright pink temporarily. They are unique among dolphins for having molar-like teeth and can
chew their prey. Also another uniqueness is pink
dolphins have small hairs on their rostrum
which remain throughout their life. Another interesting habit is pink dolphins rest on the bottom of the river.pink
dolphins are quite solitary animals, and are
found in the main rivers of the amazon and orinoco river systems of tropical
South America. They inhabit muddy stagnant water, and during flooding will move
onto the flooded forests leaving them at risk of stranding.
