Bimini is a world-renowned "shark capital," particularly famous for its seasonal population of Great Hammerhead Sharks, which are most common between December and April. The shallow, crystal-clear waters around the islands are also home to Caribbean Reef Sharks, which are seen year-round patrolling the coral reefs. Other frequently encountered species include the Nurse Shark (often found resting on the sandy bottom), the curious Lemon Shark (often seen in the mangroves as juveniles), and the powerful Bull Shark, which can sometimes be spotted near the marinas. Bimini is also a prime spot for seeing Tiger Sharks, often alongside hammerheads during baited dives. For those seeking more elusive species, Blacktip and Blacknose sharks are occasional visitors. The Bimini Biological Field Station (Shark Lab) has spent decades researching these populations, making it one of the best-studied shark habitats in the world.
