The newest plated lizard to join the ranks of Madagascar's genus Zonosaurus is the smaller (about 6 inches / 15 cm) species tsingy.  It lives in the karst limestone formations of Ankarana, Montagne des Francais, and at least one small tsingy island.  These examples were photographed in January 2001 on an overcast rainy day.  I've viewed reliable pics that demonstrate that the species can assume outrageously vivid blues and reds at times that blow the hues on these animals away.

Somewhat like the fishscale gecko Geckolepis maculata, this lizard rolls out of large flakes of its own skin as an escape mechanism when captured.  No bleeding was observed, and it's assumed the skin regenerates quickly over lost areas.
