Uracentron flaviceps, the tropical thornytail iguana or Amazon thornytail iguana is an elusive species of medium-sized arboreal lizard found in the tropical lowlands of the Amazon rainforest. The species was described by French zoologist Alphonse Guichenot in 1855. They are considered to be ant specialists and exhibit communal nesting and a harem-style breeding system in which one male mates with and attends to multiple females. Study of this species has been impeded by difficulties collecting and observing them. Wikipedia →
