In mammals that live in the water the nippels are normally protected with a skin flap. The infant needs to push this flap aside in order to drink the milk from its mother. The flap closes to be water tight, to protect the nipples.
For species that live in both the water and on land, it can be different. Sealions for example have retractable nipples. Just something to think about I guess.
Now I want to see whale breasts

I checked, nothing to see. Elephants remain the biggest big tittie queens of the mammalian family.
