Sea Turtle Welfare: Six Species, Six Threats, and How to Help

All seven sea turtle species are endangered or threatened. They face welfare harms from bycatch, plastic ingestion, fibropapillomatosis disease, entanglement, and beach disturbance. Understanding these threats guides effective welfare action.

Key Facts

All seven sea turtle species are listed as vulnerable, endangered, or critically endangered on the IUCN Red List
Around 250,000 sea turtles are accidentally caught in fisheries annually, with significant mortality
Sea turtles mistake plastic bags for jellyfish and ingest them — gut impaction causes slow starvation and death
Fibropapillomatosis, a herpesvirus disease causing tumours on skin and internal organs, now affects over 50% of green turtles in some Hawaiian populations
Artificial lighting on nesting beaches disorients hatchlings, causing them to move inland rather than toward the sea
Climate change is feminising turtle populations — warmer sand temperatures produce more female hatchlings
Boat strikes cause injuries and deaths in coastal turtle populations
Sea turtle populations are recovering in some regions following decades of nest protection and bycatch mitigation — a conservation success story

Welfare Considerations

Sea turtle welfare harms span their entire life cycle. Hatchlings disoriented by artificial light die of dehydration or predation on beaches. Juveniles and adults entangled in fishing gear drown or suffer from restricted circulation and infection at entanglement points. Those that ingest plastic experience progressive gut impaction, malnutrition, and buoyancy problems that prevent diving. Fibropapillomatosis tumours impair vision, feeding, and movement. Boat strikes cause traumatic injuries. Yet sea turtle conservation offers one of the clearest welfare success stories: nest protection programmes, bycatch mitigation, and beach lighting management have produced genuine population recovery in species previously near extinction. This demonstrates that welfare-positive interventions at scale are achievable for marine species.

What You Can Do

Choose accommodation near nesting beaches that has wildlife-friendly lighting policies
Support Sea Turtle Conservancy and Oceanic Society nest protection and monitoring programmes
Avoid plastic bags which are major turtle ingestion hazards
Report injured or entangled sea turtles to BDMLR in the UK or equivalent rescue services
Advocate for TED (Turtle Excluder Device) requirements in all trawl fisheries in turtle habitat
Donate to Archie Carr Center for Sea Turtle Research and local conservation programmes
Participate in beach clean-up events to reduce coastal plastic near nesting beaches
