Well... Truth is that sharks can detect very small traces of blood in the water. Does that increase your risk of shark attack? Probably not. Dolphins are not typically shark food so, in general, sharks are likely to be looking elsewhere for food. Of course, if the dolphins hang out near a seal colony and the seal colony recently had a big batch of baby seals, you might have reason to worry.

so im going to the bahamas and were going to go swimming with the dolphins and i just got my period today and im goin in like 2 days. ill be wearing a tampon but will it attract sharks while im swimming with them? i dont want to put anyone in danger including myself please help
