Ever since I was a boy, I've had an issue with hammerhead sharks being called hammerhead sharks. They don't look like they have hammer heads to me. Maybe a spade or even an axe, but not a hammer. So when Jessen forwarded this photo of a hammerhead bat , I was dubious.

But then I saw the photo below, and I was sold on the name (you'll notice that I feel quite a bit of angst over biological nomenclature--talk about borrowing trouble).

Hypsignathus monstrosus (love the species name), is a native of the swamps and riverine, mangrove, and palm forests of Senegal and Angola. These two specimens are male, as demonstrated by their elaborate snouts (being a sexually dimorphic species, the females have regular fox noses).

For all you wallflowers, or men who have trouble finding dates, be thankful you aren't a hammerhead bat (as if you needed another reason). These bats practice what's known as 'arena mating'. Large groups of them gather around river beds. The males line up on trees in 10 meter intervals and begin calling out and honking to attract the females. With a group of around 150 individuals, this results in some loud vocalization. When a female chooses her mate, the male makes a buzzing noise, they copulate for 30-60 seconds, and then go their own ways. This happens twice a night during mating season. The evening session is usually much more productive, but the females do show up for the 4am round, for all those males who couldn't get their act together earlier in the night. Well, that's nice of the females. More forgiving than a lot of other species (captive mantids come to mind...).

Thanks for the photo, Jessen.
