Occurrence in Surface of the Olm (Proteus anguinus) Suggests to Approach Cave Biology Processes with More Flexibility.

The article titled "Occurrence in Surface of the Olm (Proteus anguinus) Suggests to Approach Cave Biology Processes with More Flexibility" explores the possibility that cave-dwelling animals, such as the olm salamander, can actively exploit surface environments. The study provides empirical evidence that the olm can feed on earthworms living in the soil surrounding springs. The researchers observed the olm on the surface in 15 out of 69 springs sampled, as well as in 10 caves. The article includes photographs illustrating the olm's surface activity.
