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:
“Two things in America are astonishing: the changeableness of most human behavior and the strange stability of certain principles. Men are constantly on the move, but the spirit of humanity seems almost unmoved.”
—Alexis de Tocqueville (1805–1859)
“As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.”
—Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 1 (1991)
“There is a striking dichotomy between the behavior of many women in their lives at work and in their lives as mothers. Many of the same women who are battling stereotypes on the job, who are up against unspoken assumptions about the roles of men and women, seem to accept—and in their acceptance seem to reinforce—these roles at home with both their sons and their daughters.”
—Ellen Lewis (20th century)
