Caecilians are the legless amphibians, they are rarely seen due to their fossorial habits, so moments like these are very special. This yellow headed caecilian was found in Gamboa Panama behind @amphibianrescue #amphibianresilience

Mountain yellow legged frogs aided in recovery by translocating disease resistant animals congrats to Knapp et al! www.anthropocenemagazine.org/2024/12/this...

This could be the posterfrog for what ails the world’s amphibians. But it’s staging a comeback.

Some individuals of the Sierra Nevada yellow-legged frog survived the fungal plague wiping out species around the world. Now, scientists have shown they can recolonize habitat.
