Where to see a group in a country
Nine different sharks are documented in the United States, the highest count of any guide in this catalogue, and none is Least Concern: the whale shark and the Caribbean reef shark endangered; the lemon, nurse and silky sharks Vulnerable; the tiger, bull, blue and sixgill sharks Near Threatened. All eleven places are dives, from Jupiter and the Key Largo wrecks to the Andrea Doria and Block Island.
Places come from reviewed species-place links; the species shown at each place are only those in this group.
