Herein we report “failed predation” by a Cuban Racer, Cubophis cantherigerus cantherigerus (Dipsadidae), on a Cuban Giant Anole, Anolis equestris buidei (Dactyloidae; Fig. 1). This is the first report of “failed predation” by a colubroid snake in the West Indies, and the first report of a snake attempting to prey on an anole of the crown-giant ecomorph in Cuba. At 1250 h on 7 April 2004, an adult Cubophis c. can- therigerus (ca. 750 mm SVL, 37 mm head length) and an adult female Anolis equestris buidei (ca. 165 mm SVL, 51 mm head length) fell from the thatched roof of a small rustic wooden gazebo (Fig. 2) in the protected area “Varahicacos” Fig. 1.

The snake then bit the lizard before abandoning outcomes for the prey. It might be captured and killed or it is it (Fig. 4F). We examined the lizard immediately and found captured but not killed by the potential predator. In the first that it had died. Whether the snake abandoned the lizard case, the potential prey can be consumed by detritivores and because of an insufficient gape size, because of the photogra- enter the decomposer chain directly (see Begon et al. 2006). pher’s proximity, or some combination of both is uncertain.
