Resumen
Este estudio informa sobre la depredación de un espécimen adulto de boa común Boa constrictor por parte del zorro cangrejero Cerdocyon thous en el bioma Caatinga, una región semiárida de Brasil. Tales interacciones representan casos de depredación sensible al riesgo, dada la posibilidad real de que los zorros cangrejeros resulten heridos o muertos al atacar a especímenes adultos de boa común. Se discute el probable papel de eventos climáticos extremos, como la severa y prolongada sequía que ocurrió en la región al momento de este registro, en la ocurrencia de estas interacciones tróficas entre especies.
