Although they look like snakes, they are not, they are legless lizards. They have all the attributes of a lizard and none of the snake. they have eye lids and ear openings, and can shed their tails to escape predators. They grow to about 16-20 inch, the female being slightly bigger than the male. Like lizards they come out of hiding during warm sunny mornings, finding somewhere to bask in the sun to warm up before going on the hunt for food. Slow worms will feed on slugs earth worms, and certain caterpillars, they give birth to live young, usually golden in colour, and about 4 cm in length. In the photo above, there are two possibly three hiding under a tin sheet, they will find somewhere similar in October when they go into hibernation till the weather warms up the following year. (that must be nice) They are completely harmless, and beautifully smooth to the touch.
