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).

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
Images of the bat embryo Miniopterus schreibersii fuliginosus at embryonic Stages 13-17.[5]
Bat - adult and fetal limbs[4]
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. Neurofilament is an intermediate filament protein, forming part of the neuronal cytoskeleton.

Abnormalities
Hendra Virus
- Hendra virus is a paramyxoviridae (ssRNA negative-strand virus) that mainly infects large fruit bats (flying foxes) which can be passed on to horses.
- The infection has occasionally been passed onto people who have been in close contact with an infected horse.
- There is evidence of fetal and placental infection in flying fox[6] and animal models.[7]
- There is currently insufficient information to determine whether there are developmental effects in humans.

Rabies Virus
Rabies is a fatal encephalitis that can infect humans and is caused by lyssaviruses. Lyssavirus circulation has emerged in Southeast Asian bats.[8]
