Cynolebias leptocephalus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cynolebias leptocephalus faces severe threats from habitat destruction as temporary wetlands in its native range are drained for agricultural expansion and urban development. The species' dependence on seasonal pools makes it particularly vulnerable to hydrological changes caused by water extraction and altered precipitation patterns. Pollution from agricultural runoff and livestock grazing further degrades the water quality of remaining breeding sites.
Habitat
This annual killifish inhabits temporary pools, seasonal wetlands, and shallow floodplains in South American grasslands. The species requires ephemeral water bodies that fill during rainy seasons and dry completely during drought periods, allowing their drought-resistant eggs to survive in dried sediment.
