Actually, as a frequent beachgoer when I was younger, they never elicited much of a response.
Most of them are really small, actually, and I was always was more worried about what I was about to step on, especially after I had a stingray slice through my leg (luckily it was JUST on the edge, so I literally ended up with a slice because it tore my skin on the way out and I didn’t get much venom. )
Super freaky though! The beach bit me!
