What is the Natterjack Toad?

B. Koch

The natterjack toad, Epidalea calamita, is native to many areas of Europe. It thrives in shallow waters and sandy environments and can be identified by the yellow stripe down its back. It is known for its noisy croaking and has a tendency to run instead of leaping or jumping.

Native to Europe, the natterjack toad can be found in the southern, western and northern parts of the continent. Countries to which it is native include Spain, Denmark, Sweden, western Ukraine, and Estonia. Natterjacks also live in the United Kingdom and Ireland, although they are rare in these areas.

Thriving mostly in saltwater marshes and heathland, the natterjack toad can also be found living in sandy coastal dunes. It is not unusual to find these creatures in mountains, semi-desert environments or in forest glens and meadows. Natterjacks can also be found in gardens and parks, but generally, they are attracted to areas with light, sandy soils and shallow water. As they are not very good swimmers, they cannot survive in deep waters or lakes that do not have extensive shallow areas.

Covered in a mottled dark and light brown or green pattern, sometimes with red markings, the natterjack toad is most easily identified by the thin yellow line that runs down the center of its back. At the metamorphosis stage, these toads are 0.27 to 0.39 inches (7 to 10 millimeters) long, and an adult natterjack toad may reach 1.9 to 2.8 inches (50 to 70 millimeters) long. The natterjack, also known as the running toad, can also be distinguished by its short hind legs, which keep him from jumping or leaping, requiring him to run instead.

These toads are known for their impressive vocal abilities. Some male natterjack toads can be heard several miles (1 mile = 1.6 kilometers) away. They are sometimes called Europe's noisiest amphibian.

Falling into the category of endangered toads, the natterjack is especially rare in the northern and eastern parts of its range, such as in the United Kingdom, Germany, and Estonia. This is mostly due to the loss of their habitat. The decline of heathland and sand dunes by encroaching scrub and woodland has decreased the toad's livable area, as has pollution, development, and the drying up of ponds. In the United Kingdom, efforts have been made to protect and build suitable ponds for the natterjack toad.

Frequently Asked Questions

What is unique about the Natterjack Toad's appearance?

The Natterjack Toad is distinguished by a prominent yellow line running down the middle of its back. It's smaller than common toads, with shorter limbs and a more elongated body. Its skin is warty and can vary in color from green to brown, providing excellent camouflage in its natural habitat.

Where can you typically find Natterjack Toads?

Natterjack Toads are primarily found in Western Europe, including the UK, Spain, and Portugal. They favor coastal sand dunes, heathlands, and salt marshes. These habitats provide the shallow, warm pools necessary for their breeding. Their presence indicates a healthy ecosystem, as they are sensitive to environmental changes.

What does the Natterjack Toad eat?

Natterjack Toads have a diet consisting mainly of insects, spiders, worms, and other small invertebrates. They are nocturnal feeders, using their excellent night vision and quick reflexes to catch prey. Their feeding habits help control pest populations, making them beneficial to the ecological balance.

How does the Natterjack Toad reproduce?

Reproduction for Natterjack Toads occurs in shallow, warm water bodies where the female lays strings of eggs, unlike the common toad's egg clumps. Males attract females with a distinctive mating call that can be heard on warm nights. The tadpoles develop rapidly, benefiting from the warmer waters of their chosen breeding sites.

Why is the Natterjack Toad considered an endangered species?

The Natterjack Toad is classified as endangered due to habitat loss, pollution, and disease. Coastal development and agricultural intensification have reduced their breeding and foraging grounds. Conservation efforts focus on habitat protection and restoration to ensure the survival of this species.

What conservation measures are being taken to protect the Natterjack Toad?

Conservation measures for the Natterjack Toad include habitat management, such as creating and maintaining suitable breeding ponds and protecting coastal areas from development. In some regions, captive breeding and reintroduction programs help bolster wild populations. Public awareness campaigns also play a crucial role in their conservation.
