Скачать или смотреть Marine Iguana – The Ocean-Diving Lizard of the Galápagos

The marine iguana, found only in the Galápagos Islands, is the only lizard species that feeds in the ocean. These unique reptiles dive into the Pacific to forage for algae, typically staying underwater for 5 to 10 minutes and reaching depths of up to 30 meters. With their flattened bodies and strong tails, they’re well adapted to swimming and diving.

In addition to their aquatic abilities, marine iguanas have a fascinating survival mechanism. When threatened, they can "play dead" as a defense, remaining motionless to avoid attracting predators. During this "playing dead" behavior, their heart rate may slow down as part of their stress response, helping them conserve energy and avoid detection by predators. This ability to stay still and blend into their surroundings enhances their chances of survival.

Over time, marine iguanas have also evolved to excrete excess salt through specialized glands, making them well-suited for life in the harsh, salty waters of the Galápagos. Additionally, their ability to slow their heart rate during dives allows them to efficiently use limited oxygen, helping them stay underwater longer while foraging for food.
