Eastern Slow Worm

Anguis colchica

Identification

A shiny, legless lizard often mistaken for a snake. Movable eyelids are an important distinction; colours and markings vary with age and sex.

When to look

Activity depends on warm-season conditions and available cover. Animals can remain concealed even when present.

Where to look

Woodland edges, meadows and other places with protective ground cover provide shelter. A bare, tidied surface can remove useful refuges.

Behaviour and ecology

Food and nutrition

Small invertebrates are important food. Feeding takes place close to ground cover rather than by chasing large prey.

Breeding and life cycle

Slow worms produce live young. Shelter and freedom from repeated disturbance remain important during the reproductive period.

A closer look

Losing the legs does not make an animal a snake. The slow worm retains other lizard characteristics, including the ability to shed its tail defensively.

Observation and photography

Never pick it up by the tail or lift shelters to stage photographs. Observe an animal encountered naturally and leave its cover intact.

Sources and further reading

Observe without handling or moving animals, collecting eggs or disturbing shelters. Avoid trampling pond margins. Do not lift cover objects for photographs. Do not treat a short guide as a safe snake-identification or handling manual.
