Albanian water frog

Albanian Water Frog (Pelophylax shqipericus)

The Albanian water frog, scientifically classified as Pelophylax shqipericus, is a species of true frog belonging to the family Ranidae. It is endemic to the Balkan region, with its primary distribution confined to western Albania and southern Montenegro. This amphibian is strongly associated with aquatic environments, thriving in freshwater marshes, swamps, ditches, and the vegetated edges of lakes and rivers.

Appearance and Characteristics

Adult Albanian water frogs are medium-sized, with males typically reaching lengths of approximately 71 mm (snout-to-vent) and females slightly larger, averaging around 74 mm. Their dorsal coloration varies from green to light brown, marked by prominent large spots of black or dark brown. A distinctive feature observed in some males is a bright green stripe running vertically along their backbone. During the breeding season, these spots may become less distinct, and the dorsal hue can shift to olive or grass green. Both sexes possess fully webbed feet, with webbing extending to the very tips of their toes, an adaptation suited to their aquatic lifestyle. Yellow coloration is often present around the groin area, sometimes extending onto the hind legs and belly, though the female's belly is typically cream-colored and unspotted. The vocal sacs of the males are lightly pigmented, appearing grayish or green.

Habitat and Distribution

The species is exclusively found in the Balkans, specifically in western Albania and southern Montenegro. Its preferred habitats are freshwater wetlands, including marshes, swamps, and ditches, as well as the well-vegetated banks of lakes and rivers. The northernmost extent of its range includes Lake Skadar, a significant wetland area recognized by the Ramsar Convention.

Conservation Status and Threats

The Albanian water frog is classified as an endangered species, with its populations experiencing a significant decline. Several factors contribute to this precarious status. Habitat fragmentation and degradation are major concerns, driven by the drainage of wetlands for agricultural purposes and infrastructure development. Pollution from agricultural and industrial runoff further diminishes the quality of its remaining habitat. A direct and aggressive threat is the collection of these frogs for the pet trade and food industry, which not only reduces their numbers but also introduces diseases like chytridiomycosis and non-native species into their ecosystems.

Breeding Behavior and Vocalization

Reproduction and larval development are intrinsically linked to the species' aquatic habitat. Both males and females can produce a distress call lasting several seconds. The specific advertising call of the male is noted for lacking discrete pulse groups.
