🅦ퟂAdaptation
An adaptation is a feature that is common in a population because it provides some improved function. Adaptations are well fitted to their function and are produced by natural selection.
Adaptations can take many forms: a behavior that allows better evasion of predators, a protein that functions better at body temperature, or an anatomical feature that allows the organism to access a valuable new resource — all of these might be adaptations. Many of the things that impress us most in nature are thought to be adaptations.


adaptation of snow leopard.
The leopards have very strong legs that enable them to jump long distances
 have big pads with thick fur on their feet. This helps them to travel on 
rocky surfaces. Snow leopards also use this to stop them from sinking into the snow. The leopard family has camouflaged coats, enabling them to sneak up on their prey. The double-layered coat provides insulated warmth for leopards that live in the mountains.a leopard's adaptations for survival is camouflage,hiding adaptations,and mimicry.
