Alissa Barnes of the Dakshin Foundation discovered 7 hermaphrodite bigeye houndsharks of the East Coast of India at a Port of Odhisa during a survey of fishers. The survey was to determine whether a gear change was the cause of a decrease in sharks and rays catches.

The discovery is rare in sharks; however, it is not the only time hermaphroditism was discovered in sharks. A 2005 study found a large proportion of longhead catsharks were hermaphrodites and a study in the 1990s also discovered bigeye houndsharks to be hermaphrodites not far from where the 7 sharks were caught in 2017.

Alissa is super curious about how this occurred and wants to find how whether the cause is human-related or otherwise.
