The Coral Reef System

As Tulum is a part of the Mesoamerican Reef System, the ecosystem owes its magnificence to the opulent coral reefs that stretch along its coastline. This reef system extends over 1000 km along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.

Among the most breathtaking sights in Tulum’s waters are the graceful movements of the spotted eagle ray. With their impressive wingspan and unique patterns, these magnificent creatures perform an ethereal dance as they glide effortlessly through the sea. Diving alongside these rays offers a magical experience, leaving a lasting impression of their elegance and grace.

Speaking of extraordinary, between June and September, the Yucatan Peninsula becomes a hotspot for whale shark encounters. These gentle giants, who are the world’s largest fish, migrate to the region every summer to feed in the plankton-rich waters. While classified as sharks, they don’t have any teeth and filter-feed just like their cousins, the baleen whales. Hence the name: Whale shark and nickname of the gentle giant - these sharks are very gentle and pose absolutely no threat to swimmers as they feed only on plankton. Under the guidance of experienced and ethical tour operators, swimming with these grandiose creatures will be the experience of a lifetime. Fortunately, our Whale Shark Boat tour is a responsible tourism experience that ticks off all of the above.

Also inhabiting the coastal waters of Tulum - the docile and mesmerizing nurse sharks. As elasmobranch species they are characterized by their sandy-brown coloration. The unique barbels near their nostrils help them locate prey on the ocean floor. These sharks prefer shallow waters, coral reefs, and seagrass beds, making the coastal areas near Tulum an ideal haven for them. By its nature, nurse sharks are, similarly to the whale sharks, known for their gentle temperament.

They are mostly nocturnal, spending their days resting on the sea bottom or seeking shelter in caves. Despite their size, reaching up to 4,5 meters in length, nurse sharks are generally harmless to humans and pose no threat.

Sian Ka’an: Nesting, Inhabitants and Conservation

Tulum’s beaches are vital nesting grounds for these endangered sea turtles. The Sian Ka’an Biosphere Reserve, a UNESCO World Heritage Site, encompasses a vast area that includes mangroves, beaches, wetlands, coral reefs, lagoons and tropical forests. As it serves as a vital habitat for many marine species and acts as a nursery for numerous fish and invertebrates, it additionally plays a crucial role in protecting the nesting grounds and ensuring the survival of the sea turtles.

Visitors can partake in responsible turtle watching tours, which contribute to their conservation efforts. Yearly, multiple organizations contribute to various local sea turtle conservation programs. Organizations such as Fundación Tulum, Xcaret (Xel-Há) and others work together to provide environmental education, conservation, protection and research of sea turtles. We encourage everybody to try to give a helping hand, either by volunteering, donating or both!

Within the picturesque landscapes of the biosphere reserve, one can encounter the awe-inspiring presence of magnificent aquatic mammals. Undoubtedly, we are referring to the two distinct species of manatees that grace this haven - the West Indian manatee and the Antillean manatee. These majestic marine herbivores are well known for their gentle and tranquil nature, captivating all who have the privilege of witnessing them in their natural habitat.

They are primarily found in coastal waters, estuaries, and freshwater habitats, making the diverse aquatic surroundings of the Sian Ka'an reserve an ideal home for them.

As “keystone grazers”, they feed on aquatic vegetation, controlling its growth and preventing overgrowth, which could otherwise harm other maritime life. It’s safe to say, these serene beings play a crucial role in maintaining the ecological balance of the reserve.

Whilst speaking of awe-inspiring aquatic mammals, one can surely not forget to mention the astounding dolphins that roam the coastal playgrounds of Sian Ka’an. Among the most commonly sighted species are the bottlenose dolphins and the spinner dolphins.

The bottlenose dolphin is renowned for its intelligence, social demeanor, and friendly interactions with us mere humans. They are often spotted in small groups, playfully riding the waves and performing acrobatic leaps, adding a touch of enchantment to any boat trip or coastal excursion. The spinner dolphins, on the other hand, are characterized by their impressive spinning leaps out of the water. These graceful creatures travel in large groups, sometimes numbering in the hundreds. Witnessing a pod of spinner dolphins in their natural habitat is a fascinating experience, and Tulum’s waters provide a unique opportunity to do just that.

Hidden in the lush mangroves of Sian Ka’an, are the apex predators of the biosphere - the American crocodile and the Morelet’s crocodile. Both species are well-adapted to the region’s coastal and freshwater habitats, allowing them to thrive within the diverse ecosystems of the reserve. The crocodiles play a vital role in the ecosystem as well. Their presence helps regulate populations of prey species and maintains the balance of the food chain. Whilst the American crocodile, known for its large size and powerful jaws, predominantly inhabits brackish and salt water environments, such as coastal lagoons and mangrove swamps, the Morelet’s crocodile prefers freshwater habitats like rivers, cenotes, and freshwater lagoons.

A prominent habitant of Casa Cenote or Cenote Manatí, located on Federal Highway 307 on one side of the residential area Tankah, is: Panchita! This swamp crocodile is of the Morelet’s species and became famous by calmly swimming with tourists who were on expedition in the cenote. Fortunately, Panchita is considered harmless because of her familiarity with human company and only could become hostile if humans invade her territory with her offspring in close proximity.

Mystical Cenotes: Gateways to a Subterranean World

Tulum’s marine life extends beyond its coastal shores to the mystical world of cenotes that dot the region.These natural sinkholes, formed by collapsed limestone caves, reveal a hidden subterranean world of freshwater caves and tunnels.

According to Mayan mythology, Mayans considered these cenotes to be sacred. They believed the network of cenotes and depths of the sea could guide one to Xibalba, the underground world that houses the spirits of every human after life on earth.

While not directly connected to the sea, cenotes often harbor extraordinary species such as blind cavefish and freshwater turtles, providing divers with an unparalleled opportunity to explore the enigmatic realm beneath the surface. Embark on a magical journey through this wonderous realm of cenotes during our Cenote Adventure tour. You won’t regret it!

Conservation Challenges and Efforts

While Tulum’s marine life is awe-inspiring it faces several threats, including climate change, overfishing, pollution, and habitat destruction. As previously mentioned, local organizations and conservationists are actively working to address these changes through initiatives like beach cleanups, sustainable fishing practices, and public awareness campaigns.

By organizing and offering responsible tours to the Sian Ka’an biosphere, we at Mexico Kan Tours, raise awareness about sustainable tourism and the importance of protecting the reserve. Our certified local guides and captains are trained and have a deep understanding of the area’s ecology, biodiversity, and conservation efforts.
