Menstrual Period Blood Attracts Sharks – False

One of the most widespread scuba diving urban legends among non-divers is that menstrual period blood attracts sharks. And this is completely false for a few reasons.

First, menstrual fluid consists of 50 percent blood. Second, only a small volume of water is released: nearly around 80ml/6 tablespoons as a total volume over multiple days.

Sharks can detect menstrual discharge according to Divers Alert Network (DAN), however, they have little reason to attract to them they do in case of the fresh blood. They are attracted more to any novel sensory stimulus—such as urine, splashing or noises.
