Where the name comes from

Centurio is the Roman centurion and senex is the old man: “the old centurion”. The 19th-century describer found himself facing a face with no nose leaf, reduced to a mass of fleshy folds, lumps and ridges, and read it as the lined face of a legionary in retirement. It is one of the most literary scientific names there is, and one of the few that describes an expression rather than an anatomical feature.

Characteristics

  • 01

    It has no nose leaf: the face is a relief of fleshy folds and ridges.

  • 02

    The male has a flap of skin under the chin which he raises to cover his own eyes.

  • 03

    It opens its mouth wider than almost any other bat, to bite into hard fruit.

What sets it apart

The male sleeps behind a mask. Beneath his chin he has a flap of skin which by day he pulls up over the whole face, eyes included, hooking it behind the ears: through two translucent windows he goes on seeing. When he calls to attract females, the mask stays raised and vibrates with the call. It is a structure without parallel among mammals, and for nearly two centuries it was argued whether it served for camouflage, for protection or for display — recent observations at leks say it is above all an ornament.
