There are a few things that get certain zoologists wound up. I’m not talking about extinction and Jeremy Clarkson, I’m talking about relatively meaningless* distinctions that we like to pick up on when people land on the wrong side of an invisible dichotomy. You can get blood boiling by referring to sabre-toothed “tigers” rather than “cats”; failing to say “non-avian” when referring to extinction of dinosaurs; or describing apes as monkeys (actually that’s technically true as apes evolved from monkeys and the rules of taxonomy therefore require apes to be monkeys). Among such picked-nits is the difference between horns and antlers. If only more people would remember this then fewer zoologists would die prematurely of high blood pressure… (more…)
Let’s call a spade a spade. If you look at a rhino I mean *really* look at it, go on don’t be shy there’s one right there, it’s a weird looking beast. Its great big head has tiny little eyes and its massive bulk makes it a formidable animal. The most rhino-y feature is of course the horn. A lot of animals have tusks, antlers, or maybe even horns, but no other species stumbling through evolution on a cold Pliocene day thought “I know, I’ll take this horn of mine and pop it onto my nose, hah haaah, that’ll impress the ladies”. No, they are unique. The rhino is a truly remarkable and remarkable looking animal.
So this horn, what’s it all about? Rhino horn is made of keratin. What’s that you say? Look down at the tips of your fingers (or toes if you’d prefer) and (hopefully) you will be looking at some keratin. Some of you may need to remove nail varnish before you can give your keratin a really good inspection. Yes rhino horn is made of the same stuff as finger nails. (more…)
