Predation of Rhinophrynus dorsalis (Duméril and Bibron, 1841) (Anura: Rhinophrynidae) by Leptodeira rhombifera (Günther, 1872) (Serpentes: Dipsadidae), in Guanacaste, Costa Rica

Abstract

The Mexican burrowing toad Rhinophrynus dorsalis (Duméril and Bibron, 1841) is a widely distributed species with a range that spans from southern Texas to the northwest of Costa Rica (Savage, 2002; Köhler, 2011; Leenders, 2016). In Costa Rica it is found in dry forests in the Guanacaste province, from 0 to 300 meters a.s.l. (Leenders, 2016). Most time of the year this species keeps inactive underground, surfacing only to mate during the first intense winter rains (James, 1966). Due to its behavior, it is one of the species that is little seen throughout the year (AmphibiaWeb, 2018).
