"When they are first born, salamander babies are called efts. This is their larval stage. When salamanders are at the eft stage, they live in water before moving to land. They also do not have legs at this stage; because of this fact, salamander babies are very similar to tadpoles."

There are two main types of salamanders that give birth to live young, namely the fire salamander (Salamandra salamandra) and the alpine salamander (Salamandra atra).

The most common salamander in North America is the tiger salamander. This small specimen typically grows to about 4 to 6 inches. The largest salamander is the Chinese giant salamander (Andrias davidianus).

There are ten families of salamanders that are still alive, all united under the order Urodela. Among these ten families, there are more than 600 known species of salamanders.

Skin respiration, or respiration through the skin, commonly occurs in many types of amphibians. This includes frogs and salamanders. However, in many species, skin respiration is often combined with gills or lungs. This is because it is difficult to gather enough oxygen through the skin to support biological functions.

According to research, it is highly likely that all salamanders have the ability to regenerate body parts after injury. However, the specific regeneration capabilities may vary. This means that they may be able to recover everything, from the tail, limbs, to injured organs.

When we think of the dinosaur era, we often imagine reptiles like crocodiles or alligators dominating. Other species, including many salamanders, also spent a considerable amount of time on this earth. One species of salamander, for example, was found to be 168 million years old.
