Leatherback Sea Turtle Plastic Ingestion

Leatherback sea turtles are particularly vulnerable to plastic bag ingestion due to their jellyfish-based diet, with plastic filling their stomachs and causing fatal blockages.

Key Facts

Leatherbacks are the largest sea turtle species, reaching 900 kg
They eat almost exclusively jellyfish and other soft-bodied invertebrates
Plastic bags closely mimic the visual appearance of jellyfish underwater
Over 34% of leatherbacks found dead have ingested plastic
A single large plastic bag can block the digestive tract and cause starvation
Leatherbacks are critically endangered with Pacific populations in severe decline
They migrate thousands of kilometers between feeding and nesting grounds
Ingested plastic can remain in the gut for months or years

Welfare Considerations

Leatherback turtles that ingest plastic bags suffer from a false sense of satiety while actually starving. The plastic occupies stomach space without providing nutrition, causing slow starvation. Gut blockage creates pain and digestive distress. The animal may continue migrating for thousands of kilometers in this state, unable to feed properly, until eventual death. The suffering is prolonged and preventable through reduction of single-use plastic in ocean environments.

What You Can Do

Eliminate single-use plastic bags from your household
Participate in coastal and ocean cleanup events
Support organizations lobbying for plastic bag bans and marine plastic reduction
Never release balloons that can fall into the ocean resembling jellyfish
Support leatherback nesting beach protection programs
