The crab-eating raccoon is considered one of the less studied Neotropical carnivores, once its nocturnal and inconspicuous habit difficult observations about its behavior. This species is considered a frugivorous-omnivorous species, with opportunistic habits, feeding since fruits and invertebrates to other mammals and lizards. Herein, we provide a new report of predation by crab-eating raccoon upon a paradoxal frog (Pseudis platensis) and presenting a detailed literature review about its diet. We compiled a total of 14 papers published from 1986 to 2019, which eight studies were used to characterize the diet of P. cancrivorus. The diet of P. cancrivorus was constituted by 96 animals’ taxa and 35 vegetal taxa. Our record of predation upon a frog reinforces the known generalist and opportunistic diet of P. cancrivorus, besides it is the first evidence of cathemerality for the crab-eating raccoon in Pantanal and the first report of predation upon P. platensis by a mammal.
El mapache cangrejero es considerado uno de los carnívoros del neotropico menos estudiados, debido a sus hábitos nocturno y lo que dificulta realizar observaciones sobre su comportamiento. Es considerada una especie frugívora-omnívora, con hábitos oportunistas, con una dieta que incluye desde frutas hasta invertebrados, así como otros mamíferos y lagartos. En este trabajo, proporcionamos nuevos datos sobre la predación de rana paradójica (Pseudis platensis) por un mapache cangrejero, además presentamos una revisión bibliográfica detallada sobre la dieta de este mamifero. Recopilamos un total de 14 artículos publicados de 1986 a 2019, de los cuales usamos ocho de ellos para caracterizar la dieta de P. cancrivorus. La dieta de P. cancrivorus estuvo constituida por 96 taxones de animales y 35 taxones vegetales. Nuestro registro de predación sobre P. platensis refuerza la dieta generalista y oportunista conocida para P. cancrivorus, además es la primera evidencia de catemeralidad para el mapache cangrejero en Pantanal y el primer informe de predación sobre P. platensis por parte de un mamífero.
