Salamander

Salamander is one of the unique animals, cute and funny. but it looks like a catfish but have a foot that is used for swimming. The clear color (albino) add to the beauty of this animal. Salamander is a common name of approximately 550 extant species of Amphibian. They are typically characterized by a superficially lizard-like appearance, with their slender bodies, short noses, and long tails. All known fossil salamanders and all extinct species fall under the order Caudata, while sometimes the extant species are grouped together as the Urodela.Most salamanders have four toes on their front legs and five on their rear legs. Their moist skin usually makes them reliant on habitats in or near water, or under some protection (e.g., moist ground), often in a wetland. Some salamander species are fully aquatic throughout life, some take to the water intermittently, and some are entirely terrestrial as adults. Unique among vertebrate, they are capable of regenerating lost limbs, as well as other body parts. Many of the members of the family Salamandridae are known as newst. The earliest known salamander fossils have been found in geological deposits of China and Kazakhstan, which have been dated to the middle Jurasisic period, up to 164 million (plus or minus 4 million) years ago.
