Washington -- Giant Philippine lizards, unknown to science until now, have been identified by DNA and other distinct features as a new species, scientists announced.
Long known to local Filipino tribes, the 6-foot long lizards are closely related to the world's biggest reptile, the Komodo dragon, National Geographic News reported Wednesday.
The discovery and identification of Varanus bitatawa "comes as an unprecedented surprise," a study published in the journal Biology Letters said, because the lizards' home island of Luzon is "heavily populated and highly deforested."
They probably escaped scientific detection, experts say, because reptile surveys of the mountain forests where they live have been few and far between.
