Old plastic smells delicious to sea turtlesWeathered, algae-encrusted plastic has a food-like odour that is attractive to sea turtles. Researchers wafted the scent over the tank of 15 captive-reared loggerhead sea turtles. The turtles responded with the same intensity as they did to the smell of fish and shrimp. “This 'olfactory trap' might help explain why sea turtles ingest and become entangled in plastic so frequently,” says biologist Joseph Pfaller.
