The platypus is the animal emblem of the state of New South Wales. Until the early 20th century, it was hunted for its fur, but it is now protected throughout its range.hile both male and female platypuses are born with ankle spurs, only the male's spurs produce venom, composed largely of defensin-like proteins (DLPs), three of which are unique to the platypus. The DLPs are produced by the immune system of the platypus.
