The only continent without reptiles or snakes is Antarctica. Due to its extreme cold climate and harsh environmental conditions, Antarctica does not support a habitat conducive to reptiles, which typically require warmer temperatures to thrive. This polar desert is primarily inhabited by mammals such as seals and whales, along with various species of birds, including penguins. The absence of reptiles highlights the unique ecological characteristics of Antarctica, emphasizing its role as a distinct and fragile ecosystem. Research into this environment focuses on climate change and its impacts on the region's wildlife and habitat.
