Squid Have Teeth Like Old Men

According to the Tree of Life project, Promachoteuthis sulcus is known from a single, small (25 mm ML, sex unknown) but distinctive individual from great depths in the south Atlantic Ocean.

Kevin Z? PZ? Other cephalopodanauts want to weigh in here on?

Thanks to Tim Fallon for forwarding this along. Also looks like Ugly Overload beat us to the punch but it's kind of new news... so we'll run with it.
