Behavior
Larvae are predators but tend to sit and wait for their food to come to them. Usually they feed on small invertebrates and some small vertebrates. This can include tadpoles, fish, and other salamanders. Adults usually feed on terrestrial vertebrates and invertebrates. They will eat things as large as shrews, mice, and small snakes, along with other salamanders. They will eat anything that they can catch.
Fish, weasels, water shrews, and garter snakes are a few of their predators. To help defend against these predators they have a few strong defense mechanisms to help them survive. They use toxic secretion from their skin, warning postures, a "bark" vocalization, and they will bite. An Idaho Giant salamanders bite can easily break the skin of a human.

Famous quotes containing the word behavior:
“To be told that our child’s behavior is “normal” offers little solace when our feelings are badly hurt, or when we worry that his actions are harmful at the moment or may be injurious to his future. It does not help me as a parent nor lessen my worries when my child drives carelessly, even dangerously, if I am told that this is “normal” behavior for children of his age. I’d much prefer him to deviate from the norm and be a cautious driver!”
—Bruno Bettelheim (20th century)
“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)
