A lantern shark (Etmopterus) swims above the sandy bottom at the Sandy Tongue dive site. This is a deep-water shark with bioluminescent organs for camouflage. The site is just outside the influence of the Gulf Stream, so it is not scoured of all its sediment as are the dive sites closer to land and under the Gulf Stream.
