Top best answers to the question «What is a river dolphins adaptation»
- Amazon River dolphins have several adaptations that make them unique: They have a ridge along their back rather than a dorsal fin. Unlike other dolphins, botos are able to move their heads left and right. They possess paddle-like flippers that can move in a circular motion.
A unique adaptation lets botos swim easily between trees and through tangles of branches: unfused neck vertebrae, which allows them to bend at up to a 90-degree angle. In addition, the boto's long snout comes in handy for rooting through river mud for crustaceans or darting among branches after small fish.
