A gecko is a small lizard known for its unique ability to climb walls and ceilings. They have special toe pads that allow them to stick to surfaces, making them excellent climbers. Geckos come in various colors and patterns, which help them blend into their surroundings and avoid predators. These fascinating creatures are mostly nocturnal, meaning they are active at night. Geckos communicate with each other using a variety of sounds, including chirps and clicks. They are also known for their ability to shed their tails when threatened, a process that helps them escape from predators while they regenerate a new tail over time.
