Olm

About

How olm lives

Olms are pale cave salamanders that live in underground waters and rely on senses other than sight. An olm can survive long periods with very little food in stable cave systems. River species are shaped by changing water levels, flowing currents, and narrow migration paths.

Conservation

Status and habitat pressure

Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink. Protecting olm also depends on keeping rivers, wetland habitats healthy and connected.

Vulnerable species can decline quickly when habitat loss, climate pressure, or human conflict intensifies.
