for whatever reason, i was hoping that the segment “some mammals smell underwater” would have more to do with stinky platypus’ and polar bears…

Thanks for the comment Rick. I guess I could have elaborated on the point a bit more. Cetaceans (dolphins and whales) have a rather poorly developed olfactory lobe in their brains and it is believed that smell does not play a major role in their sensory experience. That being said, they have some smelly exhalations. Not surprising considering they mostly eat fish and never brush.
Fish, on the other fins, usually have a closed circuit to their nostrils. They either have a dead-end pit or a loop that is not connected to their mouth or throat (moray eels). They may have flaps or other convolutions that help channel water past their sensory cells as they move, but they don’t breathe in and out through their nostrils like mammals do. They have gills for that
porpoisepurpose.But you got me think about the platypus and polar bears. I wonder if they are capable of using olfaction underwater. I recall that platypus are supposed to have an electro-conductivity sense along their bills, similar to sharks. And being mammals, they probably do stink.

Scientist are studying the genome of the platypus. They have discovered that platypus have genes for odor sensitivity. From the New York Times:
