 Context: Hermit crabs worldwide, known for using scavenged shells as armour, are increasingly turning to plastic waste instead, according to an ecological study using social media photos.

About Hermit Crabs:

The hermit crab (IUCN: least concern) is a unique crustacean that lacks a hard shell and utilizes old shells, particularly whelk shells, for protection. Unlike other crustaceans with a complete exoskeleton, the hermit crab has a soft and squishy back part where its abdomen is located.
