The behavioural responses of the blind cave salamander Proteus anguinus and the Pyrenean salamander Euproctus asper (a facultative cave dweller) to living and dead chironomids offered in light or in darkness were studied experimentally. Both species were able to detect and locate single prey items positioned at distances of 30 cm. Proteus responded to dead prey in light faster and captured live prey in darkness earlier than E. asper. E. asper captured live prey in light earlier than in darkness. Proteus is well equipped to search for non-visual information and used an active, mechanically and chemically guided approach in all experiments. E. asper showed a more directed, visually dominated approach behaviour with live chironomids in light, but used an active, widely foraging mode with live prey in darkness and dead prey in light. E. asper may forage successfully both in epigean and hypogean habitats.
对盲螈（Proteus anguinus）和比利牛斯蝾螈（Euproctus asper，一种兼性穴居动物）在光照或黑暗条件下对活的和死的摇蚊的行为反应进行了实验研究。两个物种都能够探测并定位位于30厘米远处的单个猎物。与比利牛斯蝾螈相比，盲螈在光照下对死猎物的反应更快，在黑暗中更早捕获活猎物。比利牛斯蝾螈在光照下比在黑暗中更早捕获活猎物。盲螈具备良好的搜索非视觉信息的能力，并且在所有实验中都采用了主动的、机械和化学引导的方法。比利牛斯蝾螈在光照下对活摇蚊表现出更具方向性、视觉主导的接近行为，但在黑暗中对活猎物和光照下对死猎物采用主动的、广泛觅食的模式。比利牛斯蝾螈可能在地表和地下栖息地都能成功觅食。
