Every herpetology student learns that all salamanders are carnivorous at all life stages, unlike frogs in which the larvae may eat a variety of foods and at least one species eats fruit as an adult. Recent work by Hill, Mendelson and Stabile (2015) has shown that a few species of sirenid salamanders willfully ingest vegetation even in the absence of animal prey associated with it. A literature review indicated that the phenomenon had been noticed during examination of stomach contents, but the observations were variously interpreted as ingestion incidental to foraging for animal prey. Future work on the digestive physiology and microbiota of sirenids is warranted.
