Another Reason to Protect Sharks: Hunting Lionfish
In the above photograph, a Caribbean reef shark races to swallow a lionfish in the Honduran Roatan Marine Park. Local divers there are working with the local shark population in hopes of teaching them that lionfish are a tasty treat -- with some success.
Antonio Busiello has a complete gallery photo-documenting their attempts with a number of exceptional shots of the work done to teach sharks to hunt the invasive species. They're a definite must-see.
