“In a way, nursing underwater is therefore similar to nursing above water: the baby stimulates the mammary glands come eject milk, and then it drinks the milk,” to write Jessica Carilli. “However, the mechanism for stimulating the milk ejection reflex must be somewhat different – in humans the babies develop a seal and also suction on the nipple stimulates the reflex. In whales and dolphins, it appears that the reflex is likely engendered when the babies bang the mammary glands; for example, milk ejection was also observed in Beluga whales bumping right into the bottom the a tank.”
