Walking sharks—including the bamboo shark and the epaulette shark—belong to the family Hemiscylliidae, a group of small, slender sharks found in tropical Indo-Pacific reef systems. These remarkable sharks are best known for their unique ability to “walk” along the seafloor using their muscular pectoral and pelvic fins, especially across tidal flats, shallow lagoons, and even exposed reef during low tide. Most walking sharks are relatively small, typically growing to around 1 meter in length, and are harmless, slow-moving, and nocturnal. The epaulette shark, in particular, is famous for its large black spot behind the pectoral fin—resembling an epaulette—and its ability to survive low-oxygen conditions, allowing it to venture into tide pools where few other sharks can go.
