YnghylchThe slow worm is neither a worm nor a snake, but is, in fact, a legless lizard - its identity is given away by its abilities to shed its tail and blink with its eyelids.
Slow worms can be found in heathland, tussocky grassland, woodland edges and rides where they can find invertebrates to eat and a sunny patch in which to sunbathe. They are often found in mature gardens and allotments, where they like hunting around the compost heap. However, if you have a cat, you are unlikely to find them in your garden as cats predate them. Like other reptiles, slow worms hibernate, usually from October to March.
