Liukukaliipperi

Liukukaliipperi (*Pleurodeles waltl*) is a species of salamander belonging to the family Plethodontidae, commonly known as the **Alpine newt** or **Waltl’s newt**. Native to parts of Europe, particularly the Pyrenees, Alps, and Apennines, it inhabits freshwater environments such as streams, ponds, and lakes. This semi-aquatic amphibian is notable for its ability to survive in both aquatic and terrestrial habitats, though it prefers moist environments.

The liukukaliipperi has a distinctive elongated body, typically reaching lengths of 10–15 centimeters, with a flattened head and four short legs. Its coloration varies but often includes shades of brown, gray, or olive with darker mottling, providing camouflage among rocks and vegetation. Unlike many salamanders, it retains its external gills throughout its life, which are visible as feathery structures along its sides, distinguishing it from closely related species.

Breeding occurs in freshwater bodies, where females lay clusters of eggs attached to submerged vegetation. The larvae, known as "axolotls" in some contexts, undergo metamorphosis into juvenile newts, though they retain gills longer than many amphibians. Liukukaliipperi plays an ecological role as both predator and prey, feeding on insects, worms, and small crustaceans while being vulnerable to birds, fish, and larger amphibians.

Conservation status varies by region, with some populations facing threats from habitat destruction, pollution, and invasive species. Efforts to protect its wetlands and regulate water quality are important for maintaining healthy populations. Due to its unique characteristics and ecological significance, the liukukaliipperi is a subject of interest in both scientific research and conservation biology.
