British reptiles are a diverse group of cold-blooded animals found across the United Kingdom. They include species such as the common lizard, slow worm, and adder. These reptiles inhabit various environments, from woodlands and heathlands to gardens and wetlands. Most British reptiles are protected by law, making it illegal to harm or disturb them. They play essential roles in their ecosystems, helping to control insect populations and serving as prey for larger animals. Conservation efforts are in place to ensure their survival, as some species face threats from habitat loss and climate change.
