California Tiger Salamander
Life Cycle
Salamanders first appeared in the Jurassic. It is believed that they evolved from lpospondyles such as the microsauria. Salamanders are considered to be the least specialized of amphibians - mainly due to their conservative body plan. One interesting feature in salamander evolution is the secondary loss of bone and it's replacement with cartilage.
