Chameleon

a species of lizard which has the faculty of changing the color of its skin

It is listed among the unclean animals in Lev. 11:30, where the Hebrew word so translated is coah (R.V., "land crocodile"). In the same verse the Hebrew tanshemeth, rendered in Authorized Version "mole," is in Revised Version "chameleon," which is the correct rendering. This animal is very common in Egypt and in the Holy Land, especially in the Jordan valley.
