I’m snorkeling just 15 yards offshore from South Water Caye, a spit of an island off southern Belize shores, when I lock eyes with a three-foot-long, nut-brown nurse shark hovering 10 feet away.
Harmless to humans, nurse sharks are often called the “puppy dogs” of the sea. These gentle bottom-feeders use small teeth to crunch shellfish as they vacuum up their prey. Though I know he’s no threat, his unmistakable shark silhouette still startles me.
