Each tiny platypus hatches from the egg with the aid of an egg tooth and fleshy nub (caruncle), structural holdovers from a reptilian past. It has lungs that it uses to breathe, just like people. WebAnswer and Explanation: A platypus is a mammal. Little fossil evidence of monotremes exists, but scientists believe that before evolving to deliver live young, most mammals laid eggs.

Breathing or respiration is the process where oxygen is taken and put into the blood stream. Simon Foden has been a freelance writer and editor since 1999. Like mammals, birds take in air and extract oxygen from it to supply body tissues, while fish respiration depends on getting the oxygen dissolved in water through organs called gills.

Gestation is at least two weeks (possibly up to a month), and incubation of the eggs takes perhaps another 6 to 10 days. On at least 18 separate occasions, vertebrates have abandoned their stomachs. Mating is a strenuous affair; in one recorded session the male was seen tightly grasping the tail of the female with his bill as she led him on an exhaustive chase. It is one of only two mammals to lay eggs (the other being the echidna), it is one of only two species of mammal capable of envenomating (the other being the shrew) and it has a beak.
