Supernumerary toes in a female New World fruit bat Artibeus lituratus. This individual was very large and pregnant, so the polydactyly evidently was no hindrance. It is hypothesized this defect was caused by inbreeding as the result of a small harem in an isolated roosting canopy.

Bats (like this epauletted fruit bat) are excellent thermoregulators. To keep warm, they wrap their wings around their bodies like a blanket. If they get too hot, these bats just lightly flap their wings to disperse some of the heat.
