Introduction
The bat (chiroptera) family consists of about 1,000 species throughout the world today (90 in Australia) and is not a common model of mammalian embryonic development.
The taxon chiroptera can also be further divided into the Megachiroptera (flying foxes) and Microchiroptera suborders. Echolocation sounds have been shown to differ in Microchiroptera (vocal cords) and Megachiroptera (tongue clicks).

Species Comparison
Carollia perspicillata
- (short-tailed fruit bat) Ovulation has a 24 hour variation with up to 2 days of variation in oviduct transit time, and gestation period is 113 - 120 days.
Myotis thysanodes and M. lucifugus
- Ovulation, fertilization, and implantation occur during the first 2 weeks of May and gestation is 50 - 60 days for both species.

Thanks to Prof Richard Behringer and Dr Chris J. Creteko Dept. of Molecular Genetics, University of Texas M. D. Anderson Cancer Center, who provided images and stage information on the embryonic development of the Carollia perspicillata bat.
Embryonic Stages - Miniopterus schreibersii fuliginosus
Limb Development
Bat - adult and fetal limbs[3]
A - Left limbs of adult Myotis ricketti. DI, DII, DIII, DIV and DV represent digits I-V of the forelimb
B, C - Left limbs of Miniopterus schreibersii fuliginosus in the Fetal Stage as an example of samples used for the Myotis ricketti libraries. Libraries Hand DI and Hand DII-V are constructed from forelimb digit I and digits II-V, respectively. Library Foot is constructed from hindlimb digits I-V.
Bar = 1 cm in A; bar = 1 mm in B and C.
Neural Development
The short-tailed fruit bat Carollia perspicillata Stage 14 embryo nervous system as identified by neurofilament antibody (brown) staining.
