Opossum
Scientists used to believe that opossums are large numbers of ticks, but now they think they do not. Wildlife scientist Cecilia Hennessy thinks this belief came from a paper called "Hosts as ecological traps for the vector of Lyme disease." Hennessy did her own study and found that opossums do not eat many ticks. She and her team looked at opossums' stomachs and found animals without bones like beetles and worms, animals with bones like amphibians and small mammals, plants including grass, leaves and seeds, and garbage.
