Above you see the tongue of the baby pygmy right whale. Whales lips aren’t flexible enough to form a suction around the mother’s nipple like human babies do.
To latch on to the mother’s nipple, a baby whale curls its tongue. A good suction is assisted by the flaps on either side of the tongue – you can see one of them above. As the baby whale gets older and is no longer suckling, the flaps will mostly disappear. Cool, huh?
