Northern
red salamander
(Pseudotriton ruber)
IDENTIFICATION: Ranges in length between 10-15.2 the record
being 18.1 cm. This large orange to bright salamander has black spots
and is one of the most spectacular in this area. Older adults may be
more purple in color. Iris of eye is usually yellow. CONSERVATION BIOLOGY:
The northern red flourish in mature, deciduous forests with clean streams.
Stream siltation and pollution limit or eradicate populations of this
species.
BREEDING/LARVAE: The season for breeding is geographically variable,
but usually does not include the coldest months of winter. Most of the
adult population breeds annually. During courtship the male rubs his
snout across the female's snout, cheeks, and chin. After this, the male
moves his body under her chin and begins to undulate his tail. The female
then straddles the male and they engage in a tail-straddle walk that
ends with the male depositing a spermatophore. The eggs are without
pigment and are attached separately in little clusters.
HABITAT: These salamanders are found under moss, stones or other
objects in or around streams.
PREDATORS: There is little documentation for predators, but they
are thought to include raccoons, skunks, some snakes, birds, and shrews.
When in fear of attack the northern red assumes a defensive position
that includes curling the body so that the head is under the raised
tail. The color of the northern red is thought to imitate that of the
red eft (Notophthalmus viridescens) for protection, and their color
usually resembles the red eft in regions where the red eft is more common.
FOOD: This species generally feeds on invertebrates and small
amphibians. The adults are opportunistic foragers and have been recorded
to eat other salamanders, snails, earthworms, spiders, insects, millipedes,
and more.
RANGE: The northern red salamander can be found southern parts
of New York southward to northern parts of Florida and westward from
Ohio to Mississippi.
