Spiny-tailed Iguana

Description:

Commonly known as spinytail iguanas or Ctenosaurs. The genus is part of the large lizard family, Iguanidae and is native to Mexico and Central America. The name is derived from two Greek words: ctenos (κτενός), meaning "comb" (referring to the comblike spines on the lizard's back and tail), and saura (σαύρα), meaning "lizard".
