The park takes a leadership role in the preservation of delicate wildlife and gives visitors the privilege of experiencing these beautiful creatures for generations to come. Let’s delve into the bountiful range of animals that call the St. Martin Nature Reserve home and discover where in the park you might spot them..

Sea: The Humpback Whale

Humpback whale - Biodiversity of St. MartinRomance is in the air, or rather the sea, between December and April for humpback whale mating season. If you are lucky enough to visit St. Martin Nature Reserve at this time you may get a glimpse of these elegant creatures during their impressive migratory route. This phenomenon can be spotted all over the magnificent island of St. Martin but these gentle giants benefit from the safety of a vast protected area. In St. Martin Nature Reserve they are free from harmful fishing nets and other human interference and can thrive in peace on an open stage.

This ample space also welcomes dolphins, sperm whales, and baleen whales, but humpback whales are a favourite among marine-life enthusiasts. They are very active creatures and show off by breaching from the water and slapping the water’s surface with their fins. The largest mammal in the world is difficult to miss, so much so that you can even spot them from shore. The island offers many boating tours to help visitors get a closer look at the humpback whales’ annual reunion in Caribbean waters. Their breathtaking show of beauty and endurance is not to be missed so follow their lead and join them for a winter vacation in St. Martin.

Coral Reef: The Barracuda

The mesmerizing coral reefs of the St. Martin Nature Reserve are a colourful visual treat teeming with remarkable marine life. This plentiful habitat is a lure for the great barracuda, a long tubular fish that can grow to be 6 feet long. They are known for their ferocity and success as ambush hunters that can reach speeds of 50 kilometres an hour. Witnessing their elongated and silvery bodies shoot through the water like a bullet is an astonishing sight. Despite their efficiency and success as apex predators, any threat to humans is low and attacks are exceedingly rare. St. Martin Nature Reserve is an ideal place to spot these “tigers of the sea” where you can witness their slender bodies weave through a vibrant underwater labyrinth.

The lithe and lively barracuda is a bucket-list-worthy animal to spy while snorkelling or diving in the park. Stable water temperatures and high visibility are a guarantee year-round and the parks’ protected reservation status increases your chance of seeing the reefs active with life. Local guides are equipped to safely lead you through the delicate ecosystem and help you spot the sly and elusive barracuda.

Beach: The Leatherback Turtle

Leatherback Turtle - Biodiversity of St. Martin’s Nature ReserveThough still not the largest animal on this list, the rare and majestic leatherback turtle is the largest species of turtle in the world and a frequent visitor to St. Martin Nature Reserve. An impressive sight to behold, these behemoth creatures dominate any landscape where you are lucky enough to spot them. These massive black and leathery turtles have existed in their current form since the age of dinosaurs but are now considered endangered. Extensive worldwide initiatives are enforced to protect them against a recent and steep decline in population. The long, protected coastline in St. Martin is the ideal pitstop for leatherbacks to find refuge during their worldwide migratory route.

Admittedly, a sighting in the water is more likely than on the beach but the elusive animal is likely to leave traces of themselves in the sand. From March to July, they leave distinct tracks when nesting on the island and occasionally lay eggs. Leatherbacks have the longest migratory path of all sea turtles, making it a true compliment that St. Martin is a stop along the way.

Land: The Green Iguana

Green Iguana - Biodiversity of St. Martin’s Nature ReserveIf you don’t have the sea legs to enjoy the enchanting waters of the St. Martin Nature Reserve then you may prefer a day of hiking on its many enjoyable footpaths. Enjoy an impressive panorama of towering hills and azure tropical waters while traipsing through the colourful desert landscape. While you enjoy the view make sure you watch your step and keep an eye out for the green iguana. These playful creatures can be found scurrying around the peaks and valleys of the park and foraging for tasty local plants. Despite what their name suggests, these cold-blooded critters come in a range of colours like blue, grey, orange, and brown in order to blend into their surroundings.

No guides are necessary as the green iguana is very common but spotting them is still an exciting spectacle. When they aren’t darting between the feet of hiking tourists and sunbathing in the tropical heat, they find homes in scattered foliage around the park including hibiscus, orchid, and aloe plants. These athletic reptiles also happen to be strong swimmers so you can greet them on Pinel Island and many other islands of the park. Masters of the art of relaxation and fun, the green iguana is a perfect example of how to enjoy St. Martin Nature Reserve

Salt Ponds and Mangroves: The Red-Billed Tropicbird

The salt ponds of the St. Martin Nature Reserve are a unique ecosystem and a marriage between land and sea. From this curious landscape sprouts the mysterious mangrove forest: a haven for local birds to nest and thrive. Many notable birds call this unusual landscape home and the most notable is the red-billed tropicbird. This gorgeous bird can be found by the coastlines of St. Martin, making a detour to the park’s salt ponds a worthwhile stop.

The red-billed tropic bird is a striking white seabird with black markings and distinct long white tail streamers. They can be spotted nesting their young in the protection of the mangrove forests and rocky oceanside cliffs. Seeing their long white plumage darting behind them as they vertical plunge dive into the sea is astounding. They show off as if they know they have an audience and the salt ponds offer the best view of this ravishing performance. Noisy but sensational, the red-billed tropicbird is a fixture of the St. Martin coastline.
