Cetaceans (whales, dolphins, etc.) are similarly eery:
[Cetaceans] may look like fish and swim like fish, but whales, dolphins, and porpoises are actually mammals. Unlike their cold-blooded neighbors, these marine animals are warm-blooded, breathe through lungs, and give birth to live offspring... An example of just how rare it is for vestigial organs to appear occurred in 1963. A herd of about 450 blue white dolphins were caught by a fisherman off the eastern coast of Japan. Of these 450 dolphins only one was observed to have rudimentary hind limbs which protruded on either side of the mammary slit (Conrad, 1983).
