I had to snorkel a few times with nurse sharks for work. they are no problem, they want nothing to do with you. If you go to compass cay in the bahamas they come up on the dock in high tide, and you can pet them. pretty cool
There's also a really good spot on Little Cayman where we snorkel with them, and turtles, every trip. They've never bothered me. But, when you're surrounded by 5 or 6, makes you wonder just a little.
