Abstract

DA SILVA, Marina X; RODRIGUES, Apolonio N. S; AZEVEDO, Fernanda C  and  LEMOS, Frederico G. Stronger together: observation on crab-eating foxes (Cerdocyon thous) cooperatively preying their potential predator. Mastozool. neotrop. [online]. 2018, vol.25, n.2, pp.499-503. ISSN 0327-9383.

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.
