When the gecko touched invertebrates, but small vertebrates such as frogs, lizards, and the frog, it immediately turned and captured and swallowed snakes are not uncommon (Meshaka 1996, 2001, 2011; the gecko.

(A) The gecko approaches the curtain support after leaving its refuge under the picture frame in the lower left corner. (B) The gecko climbs onto the curtain support and (C) contacts the Cuban Treefrog, triggering the predation event. (D) An instant later, the Cuban Treefrog has ingested the gecko, with only the tip of its tail protruding from of the frog’s mouth (arrow). (E) Ingestion is complete.
