Camels can completely close their nostrils, an adaptation that helps block sand during storms and protect their respiratory system in extreme desert environments.
Overview of the Adaptation
Closable nostrils are one of several desert-specialist features camels have evolved, alongside long eyelashes, a nictitating membrane, and physiological traits that minimise water loss and tolerate heat.
How Nostrils Close
Camels have strong, flexible nasal muscles and flaps that can contract to seal the nostrils tight, preventing inhalation of sand and dust during sandstorms and gusty conditions.
Benefits and Survival Value
By keeping sand out of their airways, camels reduce respiratory irritation and conserve moisture, improving survival and performance while travelling or foraging in abrasive desert conditions.
Practical Notes
When observing or handling camels in windy, sandy environments, avoid forcing them to breathe through obstructed nostrils and respect signs of distress; their nostril-closing ability is protective but not a substitute for humane handling in extreme weather.
