037 Chameleon Comeback

00:0000:00

Chameleons -- perhaps one of the most instantly identifiable herp out there. But beyond their strange morphological adaptations what do we know about their lives. We check out a couple of papers looking at the lives of some East African species who until recently were missing some pretty basic natural history information. They are joined by a newly described species from the hills of Tanzania. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com

Revisiting the world of crocodilians, we take a look at the habitat shared by two Southeast Asian species, and discuss Siamese crocodile conservation. Our Species of the Bi-week is not a crocodile, but it is pretty scaly.
