The European spadefoot toad, specifically the common spadefoot (Pelobates fuscus), is an amphibian belonging to the family Pelobatidae. This species is native to Central and Eastern Europe, extending into parts of Western Asia.
Physical Characteristics The European spadefoot toad is a small-to-medium-sized amphibian, typically measuring between 4 and 8 centimeters in length. Its skin is relatively smooth compared to "true toads" of the family Bufonidae and often features a pattern of brown or grey blotches on a lighter background. One of its most defining morphological features is the vertical, cat-like pupil of the eye. On each hind foot, the species possesses a hard, keratinized tubercle known as a "spade," which is used for digging.
Behavior and Habitat The species is primarily nocturnal and fossorial, spending significant time underground. It prefers habitats with loose, sandy, or loamy soil, which facilitates its burrowing behavior. When threatened, the toad can inflate its body and emit a loud, alarm-like call. It may also secrete a substance from its skin that has a distinctive odor, sometimes compared to garlic, which serves as a deterrent to predators.
Diet and Life Cycle The diet of the European spadefoot toad consists mainly of various invertebrates, including insects, spiders, and earthworms. Breeding typically occurs in the spring in still bodies of water, such as ponds or flooded fields. The vocalizations of the males are relatively quiet and are produced underwater. A notable characteristic of this species is the size of its larvae; the tadpoles can grow significantly larger than the adult toads, sometimes reaching lengths of 10 to 17 centimeters before undergoing metamorphosis.
Conservation Status While the species has a broad distribution, it faces threats in various regions due to habitat loss, the drainage of wetlands, and the intensification of agricultural practices. It is protected under various international and national regulations, including the Bern Convention and the European Union’s Habitats Directive.
