USCGC Spar- Beaufort, North Carolina

You’ll feel like you’re being followed — and you’ll be right. Sand tiger sharks, also known as ragged tooth sharks — or “raggies” — aren’t an aggressive species, but they are exceptionally curious and seemingly enjoy playing chicken with divers. They swarm this 180-foot-long wreck in groups of six or more, joined by schools of amberjack, vermilion snapper, Atlantic spadefish and silversides.
