Hazards in hanging gardens: A report on failures of recognition by green turtles and their conservation implications

• Feeding behavior of green turtles was observed on the coast of Brazil.
• Evidence of consumption of synthetic rope fragments is reported.
• Implications for the conservation of this endangered species are discussed.

Marine species are experiencing unprecedented global impacts due to anthropogenic debris. Many recent studies have pointed out the hazards associated with marine litter ingestion, especially plastic debris – the most abundant and ubiquitous items in coastal and oceanic environments worldwide. In this study we provide the first in situ evidence of consumption of non-discarded synthetic rope fragments by green turtles. We explored the environmental risks to this endangered species associated with the grazing and consumption of anthropogenic debris in zones of human activity. Efforts to combat debris ingestion and reduce anthropogenic debris discharged into the world's oceans should be a priority for decision-makers and will need to involve multiple-approaches and the adoption of more environmentally friendly products and practices by the international community.
