platypus only have a few predators in the wild, this is because they hunt beneath the surface and have poison spines on their front fore arms.
the platypus' main hunter is the human but feral cats can eat them to.
Natural predators of the platypus include snakes, water rats, goannas, spotted quolls, eels, hawks, owls and eagles. In the north of its range, dingoes are another predator. Lower platypus numbers in far northern Australia are possibly due to predation by crocodiles. On occasion, large freshwater eels (which may be twice the length of a platypus) have been thought to take platypuses.
