Biofluorescence in a three-toed amphiuma. The three-toed amphiuma looks rather eel-like, with an elongate, dark gray-black, or brown colored body, and tiny vestigial legs. A large salamander, one record sized individual was recorded at 41.25 inches (104.8 cm), but 18–30 inches (46–76 cm) is the typical size of an average adult. [3]

The association of the salamander with fire appeared first in Antiquity with Aristotle (History of Animals 5, 17) and with Pliny the Elder writing in his Natural History (10, 86) that "A salamander is so cold that it puts out fire on contact. It vomits from its mouth a milky liquid; if this liquid touches any part of the human body, it causes ...
Scientists have determined that a giant salamander previously housed at the London Zoo not only represents a newly discovered species — it's also likely the largest amphibian known to man.
Greater siren out of water. Greater sirens are carnivorous and prey upon invertebrates (such as insects, crustaceans, gastropods, bivalves, spiders, molluscs, and crayfish) [11] and aquatic vertebrates (such as small fish) [11] with a possible preference for molluscs (such as snails and freshwater clams), [8] [12] although they have been observed to eat vegetation such as algae.
Description [ edit ] Two-toed amphiumas are the most prominent in the Amphiumidae family and the longest salamander species in the United States, [ 4 ] that can grow from 39 to 1,042 g (1.4 to 36.8 oz) in mass and from 34.8 to 116 cm (13.7 to 45.7 in) in length.
These salamanders are mostly terrestrial and eat invertebrates, although some species are known to eat smaller salamanders. They can be found throughout the US and some areas of Canada in damp forests or plains.
