Philippine sailfin lizard (Hydrosaurus pustulatus). Sailfin dragonsare a group of large-bodied lizards from the tropical regions of
eastern Indonesia, New Guinea and the Philippines. The largest of the
agamid family, these water-loving lizards are usually found basking in
or near mountain streams. They flee at the first sight of danger,
typically running bipedally into the water until they sink and swim
away. Their ability to hide underwater for up to an hour helps to ensure
any threats pass.Photo credit: John Steele
