General: The Spotted Salamander
is one of the larger members of the mole salamander family reaching lengths
of nearly 8 inches or more. The dorsal background color is black, dark brown
or dark gray with a slate gray belly. Young individuals sometimes have a
dark brown background color. The background color is broken up by the
presence of yellow spots arranged in two irregular rows running along the
sides from the head to the tail. The first pair of spots (from the head) are
usually orange. They are most likely to be confused with the Eastern Tiger
Salamander, but the yellow spots on this species are more irregular in both
form and placement.
They have the ability to drop their tails, to
distract predators. If a predator of the spotted salamander manages to
dismember a part of a leg, tail, or even parts of the brain/head, then it
can grow back a new one, although this takes a massive amount of energy. The
spotted salamander, like other salamanders show great regenerative
abilities, even being able to regenerate limbs and parts of organs. They
have large poison glands around the back and neck, which release a toxic
white liquid.
Average Size: Average size of an
adult is 5-8 inches long, with some over 9 inches long
Life
Span: Spotted salamanders may live more than 20 years
Diet: Spotted salamanders eat invertebrates such as
earthworms and insects or anything else they can catch and swallow. So what
other small frogs, newts etc would eat is what the spotted salamander would
eat.
Habitat: Spotted salamanders are common in
bottomland forests near floodplains, but also occur in upland forests and in
mountainous regions. Like other closely related species of mole salamanders,
spotted salamanders spend most of their lives on land and migrate to ponds
for breeding. Nearly all of their time is spent underground in burrows of
other animals. Occasionally, they are found above ground on damp or humid
nights. The only time they are found above ground in numbers are during
heavy spring and fall rains while they migrate to and from overwintering
sites.
Normal Behavior and Interaction: Spotted
salamanders are fairly solitary animals. Interaction is mostly during
breeding season. The adults migrate to the breeding ponds during periods of
heavy snowmelt, warm spring rains, or humid nights if there is no rain. The
two pictures here were taken during a spring migration in Binghamton, New
York. There were over one-hundred spotted salamanders attempting to cross a
road - they were protected by a group of SUNY - Binghamton students that
kept them from being run over by cars. It is thought this is not uncommon
and that migrations appear to be synchronized.
Males court the
females by nudging and rubbing them with their snouts. The male drops a
spermatophore, which the female walks over and picks up with her cloacal
lips. Males may drop nearly 100 spermatophores in a season. The breeding
period lasts from a couple nights to over a week. The time varies by
location. The females then lay from 1 to 200 eggs in a globular mass. The
mass is attached to twigs or other underwater structures; very rarely they
are laid on the bottom. The mass is covered with a jelly-like coating which
may be clear or white. The eggs hatch in only a few weeks. The larvae
actively feed and grow for 2 to 4 months. The larval stage varies based on
geographic location and water temperature.

Larvae will transform
into adults in two to four months. Until that time they will continue living
in water, eating insect larvae, water fleas, and other small creatures. If
there isn't enough food, they will even eat each other.
When they
leave the water as adults, the young salamanders are about two and a half
inches long. They survive best in ponds that do not contain fish, which will
eat larvae.
It has been written that acid rain has greatly diminished
this species. The ponds have become too acid for eggs to develop thus
causing whole areas to die out.
Territory: Spotted salamanders Range as far east as
Maine - west to the Great Lakes, South to Louisiana and Georgia.
