Species group: Norops auratus Species Group (fide Nicholson et al. 2012)
Habitat: semi-aquatic; Anolis barkeri is perhaps the most distinctive species of Mexican Anolis, related to its semi-aquatic lifestyle. It is found along clear, fast-moving streams and rivers. A. barkeri escapes pursuers by diving and swimming. This unusual ecology is paralleled by morphological traits such as nearly nonexistent toepads, a long narrow body, and a strongly compressed tail with two middorsal rows of scales (Gray et al. 2016).
|Etymology||named after the collector of the holotype, R. Wright Barker.|
