@kaniini i've actually heard that if you get one of the functional ones (e.g. a bit more reinforced, not just decorative - the majority are functional), it makes swimming much more efficient! ...after all, you're pasting a fin onto yourself lmao. the trick is just changing motions to be more dolphin-like instead of kicking.
but i think most people use them scuba diving or holding their breath for at least awhile. there are still some places that have mermaid performers working >
@kaniini tho it used to be a much bigger thing as a like 1960's tourist trap lol - one of the groups still doing 'mermaid shows' is actually at a site that used to be a roadside attraction, and now is a nature preserve, so the mermaids are state employees and they get to put on much the same show that has been there for decades :D https://www.roadsideamerica.com/story/2068 it's hard work for sure - basically underwater theater - but the tails actually help somewhat these days!
