A Surgical Approach to Dissection of an Exotic Animal

An Australian black flying fox – missing an ear, but fit for release.

Bats. They’re amazing creatures. Long-lived (with relevance to their body size), echolocating (for microbats and some megabats), metabolically-resilient (apparently resilient to most virus infections) flying mammals (with heart beats up to 1200 bpm for hours during flight). There are 1,411 species of this incredible creature. But very little is known about their physiology and unique biological traits. And detailed evolutionary analysis has only just begun.

The problem is, they’re an ‘exotic’ animal (wildlife that most people do not come into contact with). Being a long-lived animal producing minimal offspring (most only have one baby per year), they’re not suited to the kind of experimental studies we do with other animals like mice. Unavoidably, some aspects of biology require the use of tissues and cells. These samples can be used for sequencing, genomics, molecular evolution studies, detailed transcriptomic analysis, functional experiments with specific cell types and much more. Some methodology is beginning to be published – such as capture techniques and wing punch/genomic isolation – but there’s been an absence of protocols for the processing of bats. This is essential for the field to maximise the potential application of each individual and for minimising non-essential specimen collection.
