San Blas is home to some of the most incredible marine life in the Caribbean, but few encounters are as unexpected and exciting as meeting a nurse shark up close. These gentle giants are known for their calm nature and curious personality, making them one of the few shark species you can comfortably swim alongside.
An Unforgettable Encounter at Sea
One morning, as we anchored in the crystal-clear waters of San Blas, a group of local fishermen paddled up to our sailboat to sell their fresh catch, just as they do almost every day. As we gathered in the cockpit, watching them clean the fish, we tossed the leftover scraps into the sea.
And that’s when it happened.
A large shadow emerged from beneath the boat, gliding effortlessly through the water. The “dog shark,” as we like to call it, had arrived—a curious and friendly nurse shark, drawn by the scent of fresh fish. With slow, deliberate movements, it approached our ladder, nudging it gently as if greeting us.
One of our guests, unable to resist the thrill of the moment, jumped into the water with their snorkeling gear to swim alongside this peaceful ocean giant.
What Makes Nurse Sharks Special?
✅ Completely Harmless: Unlike predatory sharks, nurse sharks don’t hunt large prey. Instead, they feed on crustaceans, fish, and squid, making them safe to swim with.
✅ Masters of Relaxation: Unlike most sharks that must constantly swim to breathe, nurse sharks can stay motionless while pumping water through their gills—making them experts at underwater naps!
✅ Up to 4 Meters Long: Despite their size, these slow-moving sharks pose no threat to humans.
📌 Did you know?
Nurse sharks have thousands of tiny teeth! While they’re not aggressive, they use their strong jaws to crush shellfish like crabs and lobsters.
