Stronger together: Observation on crab-eating foxes (cerdocyon thous) cooperatively preying their potential predator

Abstract

We describe the first record of cooperative predation by two crab-eating foxes (Cerdocyon thous) upon an adult short-tailed boa (Boa constrictor amarali) at a Brazilian Cerrado spot. Although it is known that C. thous forages in pairs or in small family groups, there has been no report of crab-eating foxes preying cooperatively on medium and large-sized preys until now. Our observation sheds light on a poorly-known aspect of feeding behavior of C. thous that could not be recorded through scat analysis, which is currently main source of information on carnivores’ feeding ecology.
