The smalltooth sawfish
1. Residents in Crystal River are worried about a sand mine disrupting their drinking water and springs. 2. The smalltooth sawfish is one of the most unusual looking animals in the animal kingdom. Tony Wiley has been studying the species for more than 25 years, most recently with her Havenworth Coastal Conservation organization. Tonya joins us to discuss this endangered species, how it has hung on in Florida while being wiped out elsewhere, and the latest threat to its survival.
