Adaptation in desert animals:
- Desert animals have thick skin that helps reduce water loss from their bodies, which is essential because water is very scarce in deserts.
- Animals like camels have long legs with flat, cushioned soles that help them walk on hot sand without sinking.
- Camels and other desert animals have folds of skin to protect their nostrils from sand and dust during desert storms.
- Their long, thick eyelashes shield their eyes from the desert sand and bright sunlight.
- Animals like rats, snakes, spiders, and lizards stay in deep burrows during the hot daytime to avoid heat and come out at night when it’s cooler.
These adaptations help desert animals survive in hot, dry environments with little water.
