Hermit Crab Trapped in Old Tyres

Hermit Crab Trapped in Old Tyres

Discarded tyres in the oceans are trapping hermit crabs, with no way out.

Through a phenomenon called "ghost fishing," discarded tyres on the ocean floor are trapping hermit crabs.

Hermit crabs are finding their way into discarded tyres in the ocean -- and they can't get out, a new study from Hirosaki University found.

The concave interior of a car tyre can trap hermit crabs that go there in search of food and shelter. The study refers to this phenomenon -- when marine animals get caught in human litter, such as fishing nets -- as "ghost fishing."
