Eurycea bislineata Northern Two-lined Salamander / Salamandre à deux lignes du Nord Description The Northern Two-lined Salamander has a yellowish band down its back, bordered by two black lines.
Adults can grow to a length of 12 cm, with the tail making up approximately half of this. Confusing Species The Dusky Salamander is somewhat similar to the Two-lined Salamander. In Quebec they are often found in the same habitats. The Dusky Salamander can be quickly identified by the light-coloured band that runs diagonally from the eye to the jaw. The rare Allegheny Mountain Dusky Salamander of southern Québec is also quite similar to the Two-lined Salamander. Distribution Absent from south-western Ontario, the Two-lined Salamander is found throughout much of eastern Ontario, and much of Quebec, Labrador and New Brunswick.
Habitat Two-lined Salamanders are generally found close to streams because they dehydrate more readily than other lungless salamanders. Culture Species Entry - Eurycea - Two-lined and Junaluska. Description: Two-lined salamanders are a closely related complex of small (up to 12 cm in length), slender salamanders that occur in the eastern half of North America. Currently there are three recognized species, but there is still debate over how many species should be recognized. There is a yet-to-be-described species from the Carolinas, and Eurycea aquatica is still officially recognized as a species by some authorities, though most researchers now agree it is a form of Eurycea cirrigera. As more is learned about the genetics and interactions among populations, it is probable that more species will be officially described in the future.
The very rare Junaluska salamander enjoys complete protection throughout its range and is not available legally in captivity. It is included here only for the sake of information and because it is so closely related to the two-lined salamanders. Eurycea junaluska Natural Range and Habitat: Housing: All two-lined salamanders are easily kept in aquaria. Eurycea bislineata. Geographic Range The range of Eurycea bislineata, the Northern two-lined salamander, extends south from southern Quebec and New Brunswick to northern Virginia, and west from New England to northeastern Ohio (Harding 1997).
Habitat Adult Northern two-lined salamanders prefer woodland or open habitats with sufficient cover provided by layers of fallen leaves, logs, or rocks. Although occasionally found several meters from a water source, adult salamanders commonly occur along stream banks. Adults may remain active in springs, streams, or water laden soil where temperatures are above freezing in winter months. Physical Description Adult Northern two-lined salamanders, 6.4 to 12.1 cm in length, are characterized by a broad stripe stretching from head to tail along their slender bodies.

An Overview of why Salamander Conservation is Needed. By Matt Ellerbeck - Salamander Conservationist Although they are rarely given much thought, and often overlooked when they are, salamanders are in a terrible crisis. Around half of all the world’s salamander species are listed as threatened by the International Union for Conservation of Nature (IUCN). These species are all facing a high risk of extinction. A further 62 species have been designated as near-threatened with populations rapidly dwindling. Salamanders have been on the earth for over 160 million years, and the terrible state that they now find themselves in is due to the detrimental acts of humans.
For many people the thought of declining species conjures up images of exotic animals found in far away lands. Several of Ontario's salamander species have be designated as Species At Risk. One of the biggest issues affecting salamanders is the loss of their natural habitat.
