The Thylacine and the Platypus

I asked this question yesterday about this depiction: “What is wrong with this picture?”
What I was looking for is that the size is all wrong. A thylacine was as big a Labrador (of the standard size).
The platypus is 17-20 inches long, and it weighs 1.5 to 5 pounds.
It is far smaller in the real world than this depiction suggests.
Even a thylacine cub that was of the age in which it could hunt would still be much larger than a platypus.
Now, one of the comments said that platypuses don’t exist in Tasmania.
Well, actually they do.
The darker shade on this map represents the platypus’s range:

Now, I must admit that the only reason why I knew they were found in Tasmania is because I used to watch the Crocodile Hunter rather religiously.
The only episode that included a platypus was the episode in which he wandered around Tasmania.
I notice that this platypus has spurs, which means it’s a male. These spurs deliver a venom that can kill a dog. A platypus of the size of the one in that picture probably could kill a horse!
