Pacific Giant Salamander (Dicamptodon tenebrosus)

The Pacific Giant Salamander, a large species endemic to the Pacific Northwest in North America, can grow up to 13.4 inches. It typically has dark brown to black backs, adorned by light brown spots or marbling, and lighter underbellies.

This salamander prefers semi-aquatic habitats, favoring small-to-mid-sized streams and riverside forests.

Pacific Giant Salamanders get vocal if disturbed, emitting a distinct "bark." Adopting a defensive pose, it arches its body, thrashes its tail, and when the need arises, repels predators by secreting a noxious substance. Adults can also head-butt and bite.
