Dwarfism in a Seba’s short-tailed bat, Carollia perspicillata, with comments on its flight aerodynamics

We describe the first known case of disproportionate dwarfism in bats. The specimen is an adult male Seba's short-tailed bat, Carollia perspicillata (Linnaeus, 1758), captured in a ground-level mist-net during a survey in a lowland Atlantic Forest area in southeastern Brazil. Examination of the specimen skull showed craniofacial anomalies, including microdontia in the upper incisors, oligodontia in the third upper molars, fusion of the nasal septum and the left ventral nasal concha, and a narrower foramen magnum. Post cranial changes were mainly related to shortened radius, tibia and metacarpals, compared to the reference sample in multivariate space. Given its unusual morphology with short wings and average body mass, the dwarf would have higher wing loading, fly faster, require more power to fly, and have a shorter flight range compared to the species pattern. Because it presented good body condition and reached adulthood, possible mechanisms of functional compensation are discussed.
