Photos and notes from Bianka Sanó, a Dominican biology student interested in herpetology:

On the morning of December 26 2016, at 0940 h, in Haina, San Cristóbal, two males of the genus Anolis, belonging to different ecomorphs, A. distichus (trunk), and A. chlorocyanus (trunk-crown), were observed engaged in combat. The lizards were found on a concrete substrate both biting each other on the dorsum (A. distichus held its bite closer to the forelimbs), and remained motionless for approximately 30 seconds. In spite of the A. chlorocyanus being of a larger size, his opponent seemed to be taking the lead in the confrontation; subsequently the A. chlorocyanus got off the engagement and in its attempt to escape, the A. distichus attacked again by biting the A. chlorocyanus in the same place, but this time the A. chlorocyanus failed to reach its opponent in order to defend itself. After about 20 minutes the A. distichus released his opponent and the two went in opposite directions, and while in the move, it was noticeable that both animals were injured.
