Hermit Crabs Donning Our Plastic Waste

Hermit crabs around the world are increasingly using plastic waste as a substitute for shells to protect their bodies, according to a study published in the journal Science of the Total Environment. The researchers analyzed photos taken by wildlife enthusiasts and shared online, discovering that two-thirds of hermit crab species were seen living in discarded artificial shells, mostly plastic caps. The study also found that this phenomenon is observed in all tropical regions and raises questions about the potential harm or benefits of plastic for these crustaceans. The researchers believe that the declining availability of natural snail shells may be pushing the crabs towards plastic alternatives. The findings highlight the need for greater understanding of how coastal crustaceans interact with and use plastic, as well as the potential impact on their evolution. These images serve as a reminder for humans to reuse plastics instead of discarding them, according to Mark Miodownik, a professor of materials and society at University College London.
