The only continent without reptiles or snakes is Antarctica. This unique continent, characterized by its extreme cold and icy conditions, lacks the biodiversity found in other continents. The harsh climate and lack of suitable habitats limit the presence of warm-blooded animals, cold-blooded reptiles, and insects. While penguins and seals are commonly found in Antarctic habitats, reptiles are not adapted to survive in such frigid environments. This absence of reptiles also highlights the distinct ecological conditions of Antarctica compared to other continents, which host a variety of reptilian species.
