With a Venezuelan stamp: dance to survive extinction

Whenever we think about extinction, we imagine giant animals from the Mesozoic Era or those we saw in cartoons and fables, like the tigers from Sandokan, that popular series from the late seventies. The worrying thing is that, increasingly, we are moving away from fables and it is becoming a reality that the animals we knew in our childhood are disappearing, and with them, the balance of the ecosystem.

Whenever we think about extinction, we imagine giant animals from the Mesozoic Era or those we saw in cartoons and fables, like the tigers from Sandokan, that popular series from the late seventies. The worrying thing is that, increasingly, we are moving away from fables and it is becoming a reality that the animals we knew in our childhood are disappearing, and with them, the balance of the ecosystem.

Faced with this situation, Venezuelan biologists devised a plan to repopulate an extraordinary species in one of the country's most beautiful ecosystems: Mochima National Park. In this initiative, the Foundation Institute for Advanced Studies (IDEA) is leading the effort to recover seahorse populations in this protected area.

Scientifically known as Hippocampus reidi, these animals swim with their bodies and heads held upright. They lack scales and possess bony plates covered in skin. Unlike other fish, their tails don't have fins; instead, they use them to anchor themselves to marine plants. Their biological peculiarities, which include their ability to camouflage themselves and the fact that only the male carries the eggs, have made them marine celebrities of scientific fascination and a symbol of the fragility of marine ecosystems.

In the seagrass meadows and among the roots of Mochima National Park, this small inhabitant is reclaiming its territory after years of decline due to bottom trawling and habitat degradation. The repopulation of these animals, which range in size from 20 to 30 centimeters in total length, has become the flagship marine conservation project in eastern Venezuela.

The key to this success lies not only in protecting the area, but also in aquaculture for conservation purposes. Venezuelan scientists have standardized laboratory breeding protocols that allow them to overcome the most critical stage in the life cycle of these unique fish.

These kings of the Caribbean inhabit shallow waters all over the world, although the Caribbean Sea is their preferred habitat, where coral reefs and seagrass beds provide them with a home. They cling to the vegetation with their prehensile tails to avoid being swept away by the currents.

An initiative that seeks to restore marine balance and protect biodiversity

The balance of the entire ecosystem is fundamental, and one of Venezuela's most outstanding strengths is its ability to unite efforts. This project is further proof of this, as it brings together local fishermen, communities surrounding the park, and biologists. Science is leaving the laboratory to transform the park's inhabitants into "guardians of the sea," who now understand that a live seahorse in its natural habitat attracts responsible tourism, both recreational and scientific, which generates more benefits than its illegal extraction for the souvenir market or traditional medicine.

These great dancers circle around floating objects or each other, displaying flashes of color and intertwining their tails during mating, a ritual that can last for days.

How is the proccess?

The process is divided into three fundamental phases:

1. Collection and selection: Healthy parent specimens are identified in the natural environment.
2. Controlled gestation: Taking advantage of the species' unique biology (where the male incubates the eggs in a marsupial pouch), the development of the young is monitored under optimal salinity and temperature conditions.
3. Acclimation and release: Before returning to the sea, the youngsters are trained to hunt live prey and recognize Mochima's natural shelters.

Why invest so much effort in such a small animal? In ecology, the seahorse is considered an indicator species. Its presence or absence reveals the health of the ecosystem, as they are sensitive to pollution and changes in water temperature.

Another indicator is the balance of the food chain. These aquatic horses feed on small crustaceans, thus controlling microscopic populations that could destabilize the environment.

Genetic biodiversity also benefits: by releasing specimens bred under scientific protocols, the genetic stock of wild, isolated or decimated populations is strengthened, making them more resilient to diseases.

Finally, they serve as a sentinel species: for scientists, the survival success of these released animals acts as a "thermometer." If the seahorses thrive, it means that water and seabed conservation efforts are working.

What makes the Mochima ecosystem special?

Let's begin with its strategic geography. Located between the states of Sucre and Anzoátegui, it is not only a tourist attraction but also possesses conditions that make it a unique natural sanctuary. The upwelling phenomenon: Mochima benefits from the upwelling of the Cariaco Basin, an oceanographic process in which deep, cold, nutrient-rich waters rise to the surface. This generates an exceptionally high availability of plankton, a fundamental food source for seahorses. Another key condition is the diversity of microhabitats, as it is one of the few areas in the country that combines, in a relatively small area, three critical ecosystems: mangroves, seagrass meadows, and coral reefs. The seahorse (Hippocampus ingens) needs all three for different stages of its life (shelter, feeding, and reproduction).

The legal and geographical protection afforded by its status as a National Park includes a legal framework that restricts heavy industrial activities. Furthermore, its deep bays and calm waters protect juvenile fish from strong ocean currents. Constant scientific monitoring: The presence of the Oceanographic Institute of Venezuela (UDO) in the area allows for continuous scientific monitoring, something impossible in more remote areas.

Releasing these animals in Venezuela demonstrates the country's technical capacity to manage biotechnology applied to conservation. It's not about importing solutions, but about applying local knowledge to save a native Caribbean species, setting a precedent for other marine wildlife projects in this beautiful, distinctly Venezuelan sea.
