The alpine salamander (Salamandra atra) is a shiny black salamander found in the central, eastern and Dinaric Alps, at altitudes above 700 m (2,300 ft). The western Alps are inhabited by a similar species, Lanza's alpine salamander (Salamandra lanzai), in only one small area. No differences in length are seen between the sexes (9–14 cm (3.5–5.5 in)) and the sex ratio is 1:1. Their life expectancy is at least 10 years. Unlike other salamanders, whose larvae are developed in water, the alpine salamander is a fully terrestrial species. Capture-recapture methods suggest that the species is very stationary; 12 m (39 ft) was the maximum observed distance travelled by one individual during the summer season. About 120 individuals per hectare were counted in most suitable areas with >2000 individu
