Thanks for replying. It's definitely duck-billed koala though. I thought beebeekay might be an expansion of the initials BBK meaning 'baby koala'. A bit far-fetched, I know, but other than that I'm stumped.

What's the book called? And perhaps what's the main title of the section and how are these terms listed in it? Do you see duck-billed platypus in there, too?

A suggestion, Colin. It helps all of us to follow better if you reply to the same thread rather than providing a reply in a new thread.

Sorry methos. I'm been away from here for some time and just clicked the wrong button when I wanted to "Reply". I'll do better from now on!

No need to apologize.
