A study published in Global Change Biology reveals that fiddler crabs in a polluted Colombian mangrove forest play a crucial role in cleaning up microplastics. Despite high plastic contamination, these crabs thrive by ingesting and breaking down plastics quickly. Researchers from various institutions studied the crabs' interaction with microplastics, finding significant accumulation in their bodies. However, this ability may pose health risks, as harmful nanoplastics could enter the food chain, necessitating further research on their impact on crab health and potential links to serious health issues.
