A computed tomography scan showing the final two meals of an Eastern hognose snake (Heterodon platirhinos): a salamander and a toad.

More about this image
A grant by the U.S. National Science Foundation is supporting the launch of a project that will scan 20,000 vertebrates from the Florida Museum of Natural History's collection using computed tomography (CT) scanning and make these data-rich, 3D images available to researchers, educators, students and the public via the internet.

Called the oVert project -- short for openVertebrate, the project will encompass representative specimens from more than 80% of existing vertebrate genera, and a selection of these will also be scanned with contrast-enhancing stains to characterize soft tissues.

CT scanning takes X-rays of a specimen from every angle, creating thousands of snapshots that a computer stitches together into a detailed 3D visual replica. The image can be virtually dissected, layer by layer, to expose cross sections and internal structures. The scans allow scientists to view a specimen inside and out, including its skeleton, muscles, internal organs, parasites and even its stomach contents, without touching a scalpel.

Images scanned for the project will then be housed in MorphoSource, a public database created by Duke University that scientists, educators, students or the curious can mine for 3D data on their species of interest.
