Submarines can choose the naval promotion for attacking land units... yet they can't attack land units themselves, nor can they upgrade into a unit that attacks land units...
Don't get me started on the promotions for Carriers.

Old faithful natural wonder allows construction of observatories.
That coast-only ships (Triremes and Galleases) can enter Ocean tiles if they're in your territory. *slaps forehead*
Also that Great Admirals can enter Ocean tiles when they spawn, even if you don't have Astronomy yet, so you can use them for exploration purposes.
There are a few natural wonders that count as mountains for that purpose...I read them in a previous topic but can't remember what they are now.
Edit: Found a post about it.

It increases attack power against embarked land units.
It's also not just strength when attacking, it's also *defensive* strength when being attacked BY land units - machine guns, artillery..
This is very useful to know! It felt so useless...
It makes sense for mountainous wonders to count towards observatories, however, old faithful is hardly a mountain.
