Watch a video about the SAPA project - Système Auditif du Proteus Anguinus, which aims to highlight the auditory faculties of the olm by carrying out several measurement campaigns at the Station d'Écologie Théorique et Expérimentale (SETE). It brings together a wide range of skills in acoustics, vibration, bioacoustics and biology.
Can the Proteus Anguinus produce sounds?
The aim of the SAPA project is to determine whether the cave salamander, or Proteus, can vocalize, like other salamander species, or at least produce sounds. Secondly, the researchers will attempt to identify the function and context of these sound productions (sexual attractiveness, attraction of prey, repulsion of predators...).
The results of the measurement campaign in June 2024 made it possible to record and identify sound productions by Proteus in a mesocosm. The playback experiment at the end of November 2024 consisted in identifying the functional role of these sounds by observing the reactions of the Proteus when the conspecific calls recorded using an underwater loudspeaker were re-emitted.
