Scientists in the at the Smithsonian's National Museum of Natural History use X-ray imaging to study the complex bone structure and diversity of fish. This image gallery showcases X-ray images of sharks, their relatives, and bony fish, revealing how some fish have skeletons built from cartilage while others are built from bone.
In 2012, the National Museum of Natural History displayed "," a temporary exhibit that showcased fish evolution and diversity through 40 black and white X-ray images prepared for research purposes. Each X-ray is paired with a photograph of the preserved fish specimen, demostrating the value of radiography as a means of study that does not damage or destroy the specimen. to find out where this exhibit will be shown next, through 2015.

Fish are vertebrates—animals with backbones—and have bodies supported by a bony skeleton. Variations in the skeleton, such as the number of vertebrae or the position of fins, tell the story of fish evolution, and x-rays capture that story. Before the discovery of x-rays in 1895, the only way to study fish skeletons was by slow, careful dissection, one fish at a time. But with x-ray technology, details of specimens can be recorded quickly, easily, and economically—while the specimens remain intact. The National Museum of Natural History has opened its newest temporary exhibition “X-Ray Vision: Fish Inside Out.” It features the X-ray images Smithsonian scientists use to better understand Earth’s underwater ecosystems. Visitors will be able to share in the beauty, biology and diversity of 40 breathtaking images. Specimens include such marvels as the winghead shark, a pancake batfish, a bulbous deep sea angler and an ox-eyed oreo as well as the mysterious coelacanth, a prehistoric fish thought to have gone extinct alongside the dinosaurs until it was rediscovered in 1938. The exhibition will be on display through Aug. 5, after which it will travel to 10 different cities as part of the Smithsonian Institution Traveling Exhibition Service (SITES) before completing its tour in 2015.X-Ray Vision: Fish Inside Out explores the diversity and evolution of fish through x-ray images produced by Smithsonian scientists. Although the x-rays featured in this exhibit were made for research purposes, the strikingly elegant images demonstrate the natural union of science and art. Arranged in evolutionary sequence—from fishes such as sharks and skates, which have cartilage instead of bone, to bony, spiny-finned species—these x-rays will lead you on a tour through the long stream of evolution.Summers, who is based at the UW’s , uses a small computerized tomography (CT) scanner in the back room of a lab to churn out dozens of fish scans from specimens gathered around the world. The machine works like a used in hospitals: A series of X-ray images is taken from different angles, then combined using computer processing to create three-dimensional images of the skeleton.
