La vida en los tórridos desiertos

The video explores the harsh conditions of the desert, which covers a third of the continental surface and experiences extreme temperatures and minimal rainfall. It highlights the unique adaptations of desert organisms, focusing on the camel's physical traits like its sand-colored skin and humps, which help it survive without water for extended periods. The fennecus is noted for its large ears that dissipate heat, while many desert animals exhibit behavioral adaptations, such as being crepuscular or nocturnal, to cope with the intense heat. The video emphasizes the importance of adaptation for survival in such unforgiving environments.
