About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

Over the next four years, the oVert team will CT scan 20,000 fluid-preserved specimens from U.S. museum collections, producing high-resolution anatomical data for more than 80 percent of vertebrate genera.

These digital images and 3D mesh files will be open for exploration, download and 3D printing on MorphoSource, an open-access online database. These new media will provide unprecedented global access to valuable specimens in museum collections and enhance the research value of existing data-rich specimens in iDigBio.

oVert is a multi-institutional project funded by the National Science Foundation.

Digitizing specimens through CT scanning makes it easier for museums to share their rare and important specimens. This is the holotype of the rough-footed mud turtle, Kinosternon hirtepes, from the Florida Museum herpetology collection. Florida Museum of Natural History image by Ed Stanley
