The milk swimming pools in grooves on her abdomen, allowing the younger to lap it up. 6 forty four After they hatch, the offspring are suckled for three to 4 months.
11 Pure predators include snakes , water rats , goannas , hawks , owls , and eagles Low platypus numbers in northern Australia are probably because of predation by crocodiles 44 The introduction of purple foxes in 1845 for looking may have had some affect on its numbers on the mainland. 48 Uniquely amongst mammals, it propels itself when swimming by an alternate rowing movement of the entrance feet; although all 4 feet of the platypus are webbed, the hind feet (that are held towards the physique) don't help in propulsion, but are used for steering in combination with the tail.
