One-fifth of reptiles worldwide face threat of extinction

WASHINGTON  – Even the king cobra is “susceptible.” Greater than 1 in 5 species of reptiles worldwide are threatened with extinction, in accordance with a complete new evaluation of 1000’s of species printed Wednesday within the journal Nature.
