Plastic ingestion by green turtles (Chelonia mydas) over 33 years along the coast of Texas, USA

Despite exponential growth of anthropogenic marine debris in recent decades, plastic ingestion by marine turtles in the Gulf of Mexico is not well understood. Gastrointestinal tracts were examined from 464 green turtles that stranded in Texas between 1987 and 2019, and 226 turtles ingested plastic (48.7%).

Compared to other regions, plastic ingestion was low. Small turtles (
