Marine Iguanas of the Galápagos Islands

Front

Marine iguanas are unique to the Galápagos Islands.

Back

The Galápagos Islands are home to the Marine iguana, a unique creature adapted to harsh, salty environments.

Front

Marine iguanas have specialized adaptations.

Back

Marine iguanas have evolved to thrive in salty environments, spending much time foraging for algae underwater.

Front

Marine iguanas have efficient salt glands.

Back

These glands expel excess salt absorbed from seawater, allowing iguanas to sneeze out salt without losing much water.

Front

Homeostasis in marine iguanas.

Back

The balance of salt and water in their bodies is maintained through specialized salt glands, crucial for preventing dehydration.

Front

Climate change impacts on marine iguanas.

Back

Rising ocean levels and changes in salinity due to climate change threaten the future of marine iguanas.

Marine iguanas feed on algae underwater, showcasing their adaptation to the marine environment.

Front

Marine iguanas may struggle to maintain homeostasis due to increased salt levels in their environment.

Back

Increased salt levels can lead to dehydration, stress, and a decline in the population of marine iguanas.

Front

Efficiency of marine iguana salt glands is crucial for survival in saltier water.

Back

If salt glands cannot cope with increased salinity, iguanas may face challenges in maintaining homeostasis.
