Salamanders look more like lizards than other amphibians. However, They are not dry and Scaly as lizards are, and They do not have claws.
Their gills Most salamanders lose, grow Lungs, and live on land. But some, Such as mudpuppies, hellbenders, and congo eels, Become never land dwellers. Many of them keep Their gills. Some of them never develop Lungs.
What Happened to That Salamander's Tail?
Some Kinds of salamanders have an amazing adaptation called autotomy (TOT aw uh mee). If something or someone snags the tail of one of these salamanders, the salamander can the make the tail fall off. The salamander can then Scoot to safety without its tail snagged.
That is not all that a salamander can do. After a salamander loses its tail, it can regenerate (ree JEN UHR AYT), or regrow, a new one. Some salamanders can regenerate legs, too. Some can even regenerate parts of Their spinal cord, organs, and eyes.
At first, the new tail or leg or other body part looks pale in comparison to the rest of the salamander. Eventually, the color matches perfectly.
