Crocodilians, Ancient Apex Predators
In Crocodilians, Ancient Apex Predators, evolutionary biologist Ben Garrod meets some crocodilians. This category includes crocodiles, alligators, and other similar species that use their sensitive skin to detect pressure and vibrations, especially in murky waters where their vision is limited. This unique adaptation helps them hunt and survive as an apex predator. This video is excerpted from Secrets of Skin, a documentary series exploring the natural history of the body’s largest organ.
Professor Ben Garrod explores how skin has allowed vertebrates to conquer the planet. Learn more.
Lesson Express
Q: How do crocodilians use their sense of touch in their environment?
A: Crocodilians use their sensitive skin to detect pressure and vibrations in the water, helping them to locate prey and navigate murky environments.
Q: Why can't crocodilians rely on their vision?
A: The water in which crocodilians swim is often murky, making it difficult to see clearly. They rely on their sense of touch to compensate for this lack of vision.
Q: What makes the Nile crocodile an apex predator?
A: The Nile crocodile is an apex predator because it can use its ability to jump and surprise prey, and it is capable of eating almost anything in its environment.
