Korean Salamander

The species covered here under the common name Korean salamander is Hynobius leechii. Its range includes the Korean Peninsula and northeastern China, so it should not be described as endemic only to the Republic of Korea. Korea's Hynobius genus includes several similar-looking species, whose names and distribution ranges have been clarified through taxonomic research. One brown salamander photograph must not be used to explain every species in the genus as the same animal.

A long flattened tail, four legs, a rounded head and brown-toned skin are characteristic. Adults' smooth skin differs from a lizard's scales, and unlike frogs they retain a tail in adulthood. Eggs may be observed in sac-like structures rather than a single jelly-like mass. Close species can look similar, so genetic evidence and locality are sometimes considered together. Visible spot counts alone do not establish species or age.

Adults use damp refuges such as forest leaf litter and spaces under stones, eating small invertebrates and other food. They move toward water for breeding, and aquatic larvae differ from terrestrial adults in breathing structures and body proportions. Salamander regeneration is studied, but this does not mean a lost part immediately returns perfectly under every condition. Damaging a body to observe regeneration is not ecological observation.

The forest used by adults and water where eggs and larvae develop are connected habitat. Instead of judging suitability from clear stream water alone, examine surrounding soil, leaf litter and seasonal waterways together. Turning over or moving stones to find hidden individuals may alter the microenvironment. Check distribution material from after species distinctions alongside photo provenance, and avoid describing every Korean salamander as the same endemic species.
