An extraordinary invasion of land crabs has recently astonished the inhabitants of Caibarién, located in Villa Clara province. The sight of these crabs has created viral sensations on social media platforms. Videos uploaded by individuals like J. Antonio Álvarez reveal hundreds of crabs scuttling across yards, corridors, and even making their way inside homes, scaling walls, and appearing in unexpected corners of this well-known coastal town in central Cuba.
While what are often called "crab runs" can be seen in various parts of the country during specific times of the year, the residents of Caibarién describe the scale of this event over the past three years as unusual. Last year, Oscar Valdés, a local resident, spoke to Radio Caibarién, linking the surge in crabs to the decline of agriculture in the area. "The lands used to be cultivated, but now they lie fallow. This has made the environment more conducive for crabs," he speculated, noting that his observations are based on local knowledge rather than scientific research.
The current swarms are predominantly composed of pregnant female crabs, colloquially referred to as "encased crabs." Unlike the male crabs, which are typically consumed in the region during springtime, these females have not historically been part of the local diet, raising concerns about their increasing numbers.
This phenomenon has led to discomfort and even fear among residents, who report challenges in managing the infestation and keeping their homes clean and secure. Although crabs are not inherently dangerous, they can cause minor property damage and potentially transmit diseases if not handled properly.
In other regions of the country, such as Cienfuegos and Pinar del Río, crab migrations are commonly observed between March and April when these creatures travel to the sea to lay their eggs. During this journey, many crabs are crushed by vehicles while crossing roads.
Cuba is home to approximately 288 crab species spread across more than 20 families, some of which exhibit seasonal migratory behaviors that significantly affect both urban and rural environments.
