Behavior
The spotted salamander usually makes its home in hardwood forest areas that have vernal pools. These pools are necessary for breeding. They cannot breed in most permanent pools because the fish inhabiting the pools would eat the salamander eggs and larvae. Spotted salamanders are fossorial, meaning that they spend most of their time underground. They rarely come above-ground, except after a rain or for foraging and breeding. During the winter, they hibernate underground, and are not seen again until breeding season in early March-May.
Ambystoma maculatum has several methods of defense, including hiding in burrows or leaf litter, autotomy of the tail, and a toxic milky liquid they excrete when perturbed. This secretion comes from large poison glands around the back and neck. 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. As juveniles, they spend most of their time under the leaf litter near the bottom of the pools their eggs were laid in. The larvae tend to occupy refuges in vegetation and lower their activity in the presence of predators .

Famous quotes containing the word behavior:
“Children, randomly at first, hit upon something sooner or later that is their mother’s and/or father’s Achilles’ heel, a kind of behavior that especially upsets, offends, irritates or embarrasses them. One parent dislikes name-calling, another teasing...another bathroom jokes. For the parents, this behavior my have ties back to their childhood, many have been something not allowed, forbidden, and when it appears in the child, it causes high-voltage reaction in the parent.”
—Ellen Galinsky (20th century)
“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
—William James (1842–1910)
“Anytime we react to behavior in our children that we dislike in ourselves, we need to proceed with extreme caution. The dynamics of everyday family life also have a way of repeating themselves.”
—Cathy Rindner Tempelsman (20th century)
