Pink-eared Duck - It is the only living member of the genus Malacorhynchus; a closely related, but slightly larger extinct form from New Zealand was described as Scarlett's Duck . This peculiar duck may be most closely related to the shelducks but its relationships are enigmatic. It may be closer to the Musk Duck and the stiff-tails and, formerly placed in the paraphyletic "perching ducks" it is in any case not close to the dabbling ducks.
