Eralduslind

Eralduslind is a recently described genus of small, translucent amphibians discovered in the high‑altitude wetlands of the western Himalayas. The genus was first identified in 2019 by a team of herpetologists from the University of Kathmandu and the Global Amphibian Conservation Center. The name Eralduslind is derived from “Eraldus,” the Latin term used by the researchers to reference the elusive nature of the species, and “lind,” the local term for slender, reed‑like plants that dominate the genus’s habitat.

Morphologically, members of Eralduslind are characterized by their elongated bodies, translucent skin with faint greenish iridescence, and a distinctive lateral stripe of pale blue that runs from the head to the tail. They possess webbed hind limbs adapted for efficient swimming and a dorsal fin with a uniform fin ray count of 11 to 12. The genus is distinguished from related genera by a unique combination of cranial features, including a reduced jugular flange and a specialized vomerine tooth arrangement.

The genus is currently known from two species, E. lindsprout and E. lindscale, which exhibit subtle yet consistent differences in coloration and rib-patterning. E. lindsprout inhabits shallow, marshy pools at elevations between 3,800 and 4,200 meters, while E. lindscale is found in slightly deeper, slow‑moving streams. Both species are ovoviviparous, laying eggs that develop internally until hatching, a reproductive strategy thought to increase survival in the harsh, oxygen‑poor environments of the high alpine.

Ecologically, Eralduslind plays a role as both predator and prey within its ecosystem. It filters algae and small aquatic organisms, while providing a food source for larger fish and predatory bird species. Conservation status is not yet formally assessed, but the species faces threats from climate‑change‑driven habitat loss and the introduction of non‑native predator species. Ongoing monitoring is recommended to determine population trends and develop any necessary protection measures.
