Crab Invasion Strikes Homes in Zapata Swamp: Residents Take It in Stride

An unexpected "invasion" of crabs has taken the coastal town of Caletón by surprise, situated in the Ciénaga de Zapata municipality. Hundreds of these crustaceans have overtaken streets, sidewalks, and even homes. A video posted by Eilis Raposo on Facebook captures the scene, showing the crabs scaling walls and moving en masse through the neighborhood.

Raposo commented, "Look at Caletón, my house has been invaded," sharing the images alongside the reactions of local residents. In the video, a man is heard exclaiming with a mix of surprise and resignation, "Look at this, we're going to lose our homes. At least we have crabs to eat."

While this phenomenon might seem quirky or even picturesque to outsiders, it's a common occurrence in this part of the country. Known as red crabs or "zombies," these creatures migrate annually from forested areas to the sea to spawn, especially during spring and after heavy rains, like those in May.

Environmental Concerns and Cautions

Caletón's proximity to the sea and wetland areas makes it a crucial path for the crabs' reproductive journey. Despite the humorous tone of the locals, environmental specialists warn against consuming these crustaceans. Unlike the edible moro crab, the red crab is not safe to eat. Its shell contains tungsten, a heavy metal that can accumulate in the human body and cause toxic effects.

Aside from invading homes, crabs pose a challenge for drivers: their claws can damage tires, and many are crushed while crossing roads. Authorities advise caution during these weeks, especially in the early morning and at dusk.

Impact on the Community

Although a temporary nuisance for residents, experts emphasize the importance of preserving this species, as it plays a vital role in the Cuban coastal ecosystem, providing food for various terrestrial and marine species.

In May, a massive migration of red crabs was observed on the highway connecting the city of Trinidad with the province of Cienfuegos, according to videos shared online. In early April, another notable crab invasion startled the coastal neighborhood of Caletones in Gibara, Holguín, where they entered homes and "took over" yards, rooms, and kitchens.

The mass migration of these animals tends to peak between March and May and has also been documented in other parts of Cuba, such as Caibarién or Morón. Meanwhile, in Caletón, the community faces this unusual season with a blend of wonder, discomfort, and some local humor, joking, "At least we have something to eat," despite expert advice to the contrary.
