Homonota horrida (South American Marked Gecko): Aquatic locomotion

Abstract

On 26 November 2017 at 2134 h, in at La Majadita, Valle Fértil, San Juan, Argentina (30.7152°S, 67.4940°W; WGS 84; 1006 m elev.), an adult H. horrida was observed floating on water in a slow-flowing stream (Fig. 1),while hunting hemipterans (Gerridae). The lizard was suspended on the surface of the water and swam in it, making snake-like motions, to try to capture approaching insects.
