PUERTO VALLARTA, Mexico – Long known for its sun-drenched beaches and vibrant tourism scene, Puerto Vallarta also serves as a vital habitat and transit zone for crocodiles. Each season, visitors flock here for the idyllic waters and tropical climate, unaware that these same shores double as pathways for one of the region’s most ancient reptile species.
In an exclusive interview, Dr. Pablo Hernández Hurtado, Technical Manager of the Cipactli Reptile Farm at the University of Guadalajara’s Centro Universitario de la Costa, explained that much of Puerto Vallarta’s current tourist area used to be vital wetland territory. Over the decades, urban expansion has drained estuaries and forced crocodiles to traverse the ocean or populated areas to reach what remains of their natural habitat.
“All of Puerto Vallarta is a crocodile transit area, and all of these beaches are open to tourism,” Dr. Hernández Hurtado said. “Crocodiles transit through the sea because the estuaries have shrunk due to urban growth, causing the loss of old transit channels. Sightings are mainly found on beaches right next to river mouths, such as the Ameca River, near the Boca Negra estuary. Since the 1960s, construction in areas like the Marina and the airport—once wetlands—has shrunk crocodiles’ natural habitat.”
Rain and Drought: An Ongoing Tug-of-War
Both the rainy and dry seasons affect crocodile movement. Heavy rains often increase water levels, making it easier for these reptiles to travel between wetlands. Conversely, severe drought drives crocodiles to seek new areas when familiar spots become arid.
“They are also frequently observed during the dry season,” Dr. Hernández Hurtado explained, “as the areas become dry, requiring the crocodile to move to find new wetlands.”
Despite occasional sightings near humans, crocodiles typically try to avoid contact. However, if they feel threatened, they will defend themselves.
Identifying a Crocodile’s Territory
While a resting crocodile may appear on a beach briefly, especially near river mouths, most continue moving soon after. Certain zones such as Boca Negra and Boca de Tomates—where estuaries remain—are more likely to host these reptiles.
“It’s easier to see their traces, like tail and paw prints,” Dr. Hernández Hurtado noted. “Places like the El Salado estuary are open to tourism, while the Boca Negra estuary is fenced off to prevent direct contact with crocodiles.”
Preserving Crocodile Habitat
Dr. Hernández Hurtado emphasized the importance of protecting the small but crucial estuaries, like El Salado and Boca Negra, which harbor stable but limited crocodile populations. Nesting females, in particular, require a wide berth since they can become extremely protective of their eggs.
“Through research, we’ve found only six breeding females on average. It is important not to approach their nests, as mothers can react defensively,” he said.
Safety Tips and What to Do If You Spot a Crocodile
- Avoid swimming near them: Keep a respectful distance, especially if children or pets are present.
- Do not feed or provoke them: Crocodiles may interpret any close contact as a threat.
- Call authorities immediately: Local Civil Protection services or 911 are trained to handle crocodile sightings.
With the ongoing development in Puerto Vallarta, the balance between tourism and wildlife conservation remains a delicate one. Experts like Dr. Hernández Hurtado remind residents and visitors alike that coexistence is possible through awareness, respect for wildlife habitats, and responsible tourism practices.
