. Breviora. Zoology; Paleontology. Lizard photograph by Jonathan Losos; dewlap photo- graph courtesy of Luke Mahler. One of the most remarkable of the more than 360 anole species, A. vermiculatus is always found near rivers (Leal et al, 2002), into which it dives to escape predators or to pursue prey, including small fish and shrimps. In a survey of stomach contents, Rodriguez Schettino and Novo Rodriguez (1985) found insects, crustaceans, and plant matter (flowers and fruits of palms, primarily in the stomachs of adult males). The species will run bipedally across the river surface; individuals can be seen crisscrossing as they chase each other in territorial disputes. When not in the water, these lizards perch on vertical rock walls and on tree branches, from which they dive into the water if threatened, as well as on rock outcrops within the stream (Rodriguez Schettino et al, 1987). This is one of two anoles completely lacking a dewlap (the other is its sister species, A. bartschi). Individuals use shallow head bobs to signal to each other; their complex body coloration might aid in communication (Fitch and Henderson 1987). The skin of this species has a velvety texture that might have some relationship to its aquatic DISCUSSION Natural selection often favors ecological divergence that minimizes the intensity of negative interspecific interactions among sympatric species in a community (Hutch- ison, 1959; MacArthur, 1972; Losos et al, 2003). The lizards of Soroa likely have a long history of ecological interactions (Losos et al, 2003). Our previous work, based on data reported and elaborated on here, revealed.
