Swim with the Friendliest Shark in San Blas

By Guadalupe·5 min read

One morning, as we anchored in the crystal-clear waters of San Blas, a group of local fishermen paddled up to sell their fresh catch — as they do almost every day. As we tossed leftover scraps into the sea, a large shadow emerged from beneath the boat.

The nurse shark had arrived. Curious, gentle, and completely unafraid.

An Unforgettable Encounter

With slow, deliberate movements, it approached our swim ladder, nudging it gently as if greeting us. One guest couldn't resist — they jumped into the water with their snorkeling gear to swim alongside this peaceful ocean giant.

We call it the "dog shark." It visits us regularly, drawn by the scent of fresh fish from the Kuna fishermen. And every time it shows up, it stops everyone on board in their tracks.

What Makes Nurse Sharks Special?

  • Completely harmless — they feed on crustaceans, fish, and squid, not humans
  • Masters of relaxation — unlike most sharks, nurse sharks can stay motionless while pumping water through their gills. They're experts at underwater naps
  • Up to 4 meters long — despite their size, these slow-moving sharks pose no threat whatsoever
  • Thousands of tiny teeth — used to crush shellfish like crabs and lobsters, not for hunting large prey

Snorkeling in San Blas: A Marine Wonderland

San Blas is one of the best snorkeling destinations in the Caribbean, with untouched reefs and marine life rarely seen elsewhere. What you might encounter:

  • Colorful coral reefs — brain corals, staghorn corals, and vibrant marine ecosystems
  • Exotic fish — parrotfish, angelfish, and groupers in crystal-clear water
  • Sea turtles and dolphins as frequent visitors
  • Manta rays, lobsters, and of course, nurse sharks

How to Swim with Nurse Sharks Responsibly

  • Respect the wildlife — let them come to you. Never chase or touch them
  • Stay calm — nurse sharks are curious, not aggressive. Just observe and enjoy
  • Use reef-safe sunscreen — protect the coral while you snorkel
  • Never stand on coral — it takes decades to grow and seconds to damage
"Swimming with a nurse shark in the wild is the kind of thing you call home about. It changes how you think about the ocean."
