Hermit Crabs Swap Shells for Plastic as Pollution Rises

Chetumal, Mexico — A civil group of environmentalists in the port of Mahahual has reported that some hermit crabs are using plastic tubes as makeshift shelters amid the scarcity and removal of seashells. Hermit crabs typically inhabit empty seashells, which provide them with advantages such as protection from predators, water currents (for marine species), and desiccation (for terrestrial species).

Environmental Pressures Force Adaptation

Victor Rosales, president of the civil association Aak Mahahual, explained that pollution, sargassum seaweed, and the collection of seashells as souvenirs have forced hermit crabs to seek alternative forms of protection.

“I regret that this situation is becoming increasingly common, putting the species at risk due to their vulnerability without proper shelter,” Rosales said.

He emphasized that the lack of suitable natural shells poses a significant problem for these creatures, particularly in polluted areas like the port of Mahahual.

Ecological Impact and Habitat Concerns

Hermit crabs are commonly found in coastal zones, including beaches and rocky areas, and require access to water to keep their gills moist. The growing reliance on plastic debris highlights broader environmental challenges, including marine pollution and habitat degradation.
