===Size and longevity===
Adult slow worms grow to a length of approximately 50&nbsp;cm (20"), and are known for their exceptionally long lives; the slow worm may be the longest-living lizard, living about 30 years in the wild and up to at least 54 years in captivity (this record is held by a male slow worm that lived at the [[Copenhagen Zoo]] from 1892 until 1946, the age when first obtained is unknown).<ref>{{cite web |last=Smith |first=Malcolm |date=1951 |title=The British Amphibians and Reptiles |url=http://www.newnaturalists.com/product/9780007308156/The+British+Amphibians+and+Reptiles |url-status=dead |archive-url=https://web.archive.org/web/20170916052705/http://www.newnaturalists.com/product/9780007308156/The+British+Amphibians+and+Reptiles |archive-date=2017-09-16}}</ref><ref>{{cite web |title=Slow Worm |url=http://www.fourmilab.ch/images/animal_magnetism/notasnake.html}}</ref> The female often has a stripe along the spine and dark sides, while the male may have blue spots dorsally.
