Where the name comes from

Dobsonia recalls George Edward Dobson, an Irish army surgeon who in the 19th century wrote the first world catalogue of bats and brought order to a class that until then was a muddle. Moluccensis names the Moluccas. The common name describes the feature that leaps out: the wing membranes meet along the midline of the back, and the skin beneath them is bare.

Characteristics

  • 01

    The wings attach at the centre of the back instead of at the flanks.

  • 02

    It is among the few large fruit bats able to navigate in the dark by tongue clicks.

  • 03

    It flies among close-set trunks better than flying foxes, which keep to open air.

What sets it apart

The wings attaching on the back rather than the flanks give it a manoeuvrability flying foxes do not have: it can nearly hover, turn tightly and fly inside the understorey. It is why it occupies a different niche from its relatives while eating the same things — they gather at the edges and above the canopy, it works inside the forest. The same food, two opposite ways of reaching it, and one detail of anatomy dividing them.
