Marine Iguana Climate Vulnerability

Marine iguanas of the Galapagos Islands face increasing welfare and conservation threats from climate-driven El Nino events.

Key Facts

Marine iguanas are the only sea-going lizards and are found only in the Galapagos
El Nino events reduce algae availability causing starvation events
During severe El Ninos up to 70% of the marine iguana population can die
Some populations have evolved larger body sizes allowing fasting during food scarcity

Welfare Considerations

Individual marine iguanas experience significant suffering during El Nino starvation events — progressive weight loss, weakness, and slow death over weeks. Climate change is increasing the frequency and severity of El Nino events. As a unique and irreplaceable species found only in one location, conservation of their habitat and food resources is critical.
