The largest of the Pacific Giant Salamanders live in the states of Oregon and Washington. They have a bulky head, body and large muscular legs. The Pacific giant salamander is also known as Dicamptodon Tenebrosus and Pacific Giant Salamander is a part of the genus dicamptodon, but to be specific it is in the species tenebrous and that is how its scientific name is dicamptodon tenebrosus. The Pacific Giant Salamander’s habitat mostly inhabits cool, wet coniferous forests in the environment of cold, clear and clean streams and mountain lakes. They are found around many places around the world. They are found in British Columbia and also into the northern portion of California and they are also throughout the cascade mountains are also where giant salamanders are found. [1]

Anatomy

There are many salamanders in the states Oregon and Washington, but the largest Salamander is known as the Pacific giant salamander. The Pacific giant salamander has a massive head and a very huge body. It also has large and tough legs but has very stout limbs The limbs only reach their hind limbs and it is rare for them to have black spots.[2]. They are mostly reddish-brown with a pattern of marbles across its skin. [3] But when they grow older their skin pattern becomes plain and different but the head pattern remains the same. [4] The pacific giant salamanders also have very keen eyes that are well developed and large. The tail is shorter than its head and its body length. Larvae are dark skinned and it is dorsal-ventrally flattened. At the very end of the tail is a fin, which is behind the pelvis. The tail of Larvae is flattened on each side of its body. [5] And they also have gills that are short, fringed, and very dark red. [6]

Reproduction

The reproduction of the pacific giant salamander is not very well known. Their eggs in various stages of development that have been found from the seasons spring and also in fall. But, there is little synchrony in development. Each female salamander lays about 75 to 100 eggs in covered underwater compartments in surfaces of a spring, stream, or mountain lake. Eggs have a short stalk that appends it to the rock and prevents it from being washes away by fast water. [7]

Ecology

The Salamander is the basic cold blood animal. Sometimes they come outside and increase the body temperature, because of that reason the salamander usually lives near by the warm region just like Lizrds. [8]

Regeneration of the Pacific Giant Salamander's Tail

Pacific Giant Salamanders are the superstars of regeneration. Pacific Giant Salamander' tail can grow back up that we knew that when we were young, but their legs, part of the hearts and their lenses and retinas also can grow back. Humans can't do any of these. [9] Pacific Giant Salamanders are animals that can regenerate their tails. Sometimes they cut their tails to run away from the predators. [10]
