SLOW-WORMS Anguis fragilis
- The
characteristic black dorsal stripe of a female Slow-worm Anguis fragilis is clearly
visible in the first photograph. This marking is generally absent in adult
males and the latter may sometimes develop rather attractive blue spots.
They also possess broader heads than the females and use this physical
attribute to grab potential mates (Slow-worm reproductive behaviour does
not appear to be particularly consensual!). The head markings differ
between individuals and all markings will become more faded as the old
skin loosens prior to a moult. These legless lizards (they are neither
snakes nor venomous so please do not harm them!) live mainly on
soft-bodied slugs and worms. Unlike snakes they are able to blink their
eyes - a necessary attribute when there is a need to remove slug slime
after a meal!
