Common toad (Bufo bufo)

Physical characteristics

Adults have stout bodies, short legs and rough, dry skin covered in wart-like bumps. They have horizontal pupils and lack true teeth. Prominent parotoid glands behind the eyes secrete a bitter, milky fluid containing compounds (commonly called bufotoxins) that discourage many predators. Plum-coloured, greenish-brown, olive or grey-brown colouration, often with patches of orange or red, provide camouflage among leaf litter. Locomotion is typically a slow walk or short hop rather than long leaps.

Distribution and habitat

The species occurs across most of continental Europe and into parts of western Asia, but is absent from some islands such as Ireland and Iceland, and from certain Mediterranean islands. Common toads use a mix of terrestrial habitats — woodlands, hedgerows, parks and gardens — and require nearby still or slow-moving freshwater for breeding. Seasonal movements connect feeding areas with breeding ponds and breeding sites may be revisited year after year; see regional range summaries for local details.

Behaviour, diet and life cycle

Primarily nocturnal, common toads shelter in cool, damp refuges by day and emerge at dusk to feed on invertebrates. Their diet includes beetles, slugs, earthworms and other ground-dwelling prey; more on typical prey types at invertebrate diets. Breeding usually takes place in spring, when males gather at ponds and grasp females in amplexus until eggs are deposited as long gelatinous strings. These hatch into aquatic tadpoles that develop and metamorphose into juvenile toads before dispersing to terrestrial habitat. In colder regions adults hibernate through winter in burrows, compost heaps or other sheltered sites.

Ecology, threats and conservation

The common toad is generally adaptable and often abundant where suitable breeding and terrestrial habitats exist. Local declines have been recorded and are commonly linked to loss of breeding ponds, habitat fragmentation, road mortality during spring migrations and pollution. Conservation measures include protecting and restoring breeding ponds, creating toad-friendly crossings at migration hotspots, and maintaining terrestrial refuges. For broader taxonomic and conservation context see resources on the genus Bufo.

Identification and human interactions

• Key features: dry, warty skin; parotoid glands; horizontal pupils; terrestrial habits with seasonal pond breeding.
• Behavioural notes: mainly nocturnal hunters of invertebrates; slow gait rather than long hops.
• Human contact: handle with care or avoid handling, as skin secretions can irritate and toads are sensitive to oils and salts on human skin.

Together these traits make the common toad a familiar and ecologically valuable amphibian across much of its range, commonly encountered in both wild and semi-urban landscapes and often appreciated by gardeners for its role in controlling pests.
