This is Nurse again "fluking up" to do a deep dive. Romantic as this photo may be, water dripping off her fluke and all, it is practically useless to a person trying to match it with pictures in the catalogue.... you would have to crane your head way over to see underneath.... hahaha. If you ever go on a whale watch and see a whale "fluking" wait a second longer until it's tail comes up a bit more.
I know this is Nurse because she showed her tail a few seconds later.
