Swimming Skeletons
There are a lot of fish in the sea, and one man wants to get to know all of them, inside and out. University of Washington biologist Adam Summers is on a mission to scan all 33,000 known species of fish. Summers and his team use a CT scanner to create highly detailed images of fish skeletons. CT scanners take multiple X-ray images and use computers to stitch them together.
These stunning images, which are available free online, reveal the internal structure of fish. To see the fish skeleton the team has already scanned in extreme detail, anyone can visit the website at https://osf.io/ecmz4/wiki/Fishes.
Summers scans multiple fish at a time. In one session, he scans 988 fish in batches of 13. If it takes him 304 hours to scan all the fish, how long does it take to scan each batch of 13 fish?
