Researchers are working to create a complete whale shark DNA library.

Live Science is reporting that researchers from Emory University and the Georgia Aquarium are working on a whale shark (Rhincodon typus) genome sequencing project, using the aquarium’s captive whale sharks as subjects for the project. By mapping the whale shark genome, scientists hope to learn more about the species, including its lifestyle and the genetic roots of the whale shark’s large size, according to the Live Science.

The sequencing project is expected to take months to complete.
