I posted a few weeks ago to the effect that the bee might be the only creature with an odd number (greater than one) of organs, i.e. three eyes (turns out it's actually five, of two different sorts - thanks Sue!).
I now find, courtesy of Paul the World Cup predictor, that an octopus has three hearts. How about that for over-redundancy? Even BP didn't think of putting in more than one blow-out preventer. They do, however, meet the second definition of octopus in my beloved dictionary, which is "a person or organisation with widespread influence".
Chambers usually avoids value judgements, as dictionaries should, so isn't explicit about the nature of the "widespread influence" in question; but I imagine I can see or hear the raised eyebrow and the sniff. You wouldn't call BP an octopus as a compliment, would you? Actually, it's a slight - BP doesn't have even one heart.
Sadly, your average octopus apparently lives for only three to five years, despite all those hearts (it must be exhausting keeping all those tentacles going, though). This analogy is starting to wear a bit thin, isn't it? So, to close on a lighter note, a prize to the first to answer this question: "what's the plural of octopus?"
