Sighted and enucleated Ambystoma maculatum larvae were offered a choice of large vs. small, or normally coloured vs. artificially darkened Daphnia. Salamanders in all treatments took the largest Daphnia and exhibited similar high feeding rates. There was no preference for artificially darkened Daphnia, as would be expected if visual cues predominate. Results indicate that vision is not exclusively responsible for size-selective predation by nocturnal salamanders.-from Author
