You know what I just learned? A platypus is generally smaller than a housecat.
(The website is in frames – LAME – so click on “facts” in the left nav.)
I always envisioned a platypus being about the size of a medium to large sized dog. About the size of a collie? An Australian Kelpie? A decent sized animal. But no! They are only about 45-60cm long. Cat sized.
I had no idea. I was thinking they’d be about three to five feet long. Weird.
