now sirens are kinda like newts/salamanders correct??? like a bichir....now are they the ones where it looks like their gills are on the outside of their body??? we only get salamanders in Juneau and they aren't even supposed to be there.......guess they jumped ship from prince whales island........do they freeze themselves kinda like frogs do to survive the winter??
Sirens are salamanders. They are obligate perennibranchs, meaning they keep their external gills throughout their lives. Sirens cannot to my knowledge survive being frozen, though they can tolerate near-freezing temperatures. They do cocoon themselves in mud and aestivate as lungfish do when water levels drop too low.
The salamanders in southeast Alaska are members of two families, neither closely related to sirens: the Ambystomatidae or mole salamanders, and the Salamandridae or newts. These salamanders (at least the Alaska species) have a typical amphibian life cycle with a gilled aquatic larva and air-breathing terrestrial adult.
Salamanders actually live in areas much colder than southeastern Alaska, including rather frigid parts of eastern Canada, Scandinavia, and Siberia. They mainly survive the winters by burrowing below the frost line.
