Dolphin's are mammals. So do they have nipples? If they do, do the males have superflous nipples like the males of other mammals?

IIRC, dolphins and other cetaceans squirt their milk into the water and their baby drinks it before it disperses. The milk comes out of a modified sweat gland, just like the breasts of land mammals. But they don't have nipples, as baby cetaceans don't have pursable lips to attach themselves to one.

WIGGUM,dolphins have nipples concealed (like the genitals) behind slits in the skin. The baby dolphin nurses by putting his beak in the slit and grasping a nippled. The mother then contracts special muscles that squirt milk into the baby's mouth (suckling underwater must be impossible). Each nursing episode lasts for 5 - 10 seconds, and occur 3 - 8 times per hour all day and night.
