The Sailfish of Isla Mujeres: A Spectacle of Speed
Every year, between January and February, Isla Mujeres, a few kilometers from Cancún, hosts a spectacular event: a unique « Sardine Run. » Millions of sardines gather for their migration, attracting a multitude of predators, including the impressive sailfish (Istiophorus platypterus).
Observing these creatures requires several hours of navigation on the high seas, a physical challenge rewarded by an astounding spectacle. Sites are located through the activity of seabirds, also drawn to this feast. Approach is made with fins, mask, and snorkel (PMT), as the hunt occurs at the surface, ensuring excellent visibility.
The sailfish, the fastest fish in the world, can reach speeds of 110 km/h thanks to its sail-like dorsal fin. It uses its bill to stun sardines before consuming them. The ballet, orchestrated by dozens of sailfish, lasts only a few minutes but remains etched in memory.

The Manatees of Crystal River: A Gentle Encounter in Florida
In winter, Caribbean manatees (Trichechus manatus) gather by the hundreds in the warm waters of Crystal River, north of Tampa. These marine mammals, distant cousins of dugongs and closer to elephants, are harmless and indifferent to human presence, provided observation rules are respected.
The Three Sisters Spring sanctuary, at the heart of the Crystal River National Wildlife Refuge, is a prime spot to observe these herbivores in their natural habitat. Approach is made in silence, respecting the animal. Though some tourists are tempted to touch them, it is crucial to avoid any interaction.
The Florida government implements protective measures for these vulnerable animals: combating pollution, regulating approach, and limiting boat speed to prevent collisions.

The Marine Iguanas of the Galápagos: Unique Reptiles in the World
The Galápagos archipelago is home to an exceptional concentration of endemic species, including the marine iguana, the world’s only marine lizard. Different species, endemic to each island, can be found. These reptiles bask in the sun on rocks before diving to feed on algae.
Despite their imposing size (up to 1 meter), they are herbivores and not shy, allowing divers to approach them at a reasonable distance. They move with agility underwater, clinging to rocks or swimming with their elongated bodies and undulating tails. They can hold their breath for nearly an hour and dive up to 15 meters deep.
