Why do you guys say '"duck-billed" platypus'?

Hello! I am from Australia, and I had noticed recently that a lot of you guys seem to say 'duck-billed platypus' when referring to the little guys, when here the 'duck-billed' is dropped, and seemingly everywhere else too. Is it a phenomenon from like TV or something? I've only ever referred to them as just platypuses. Just curious to know, thanks!
