George Washington University Computational Biology Director solves 200-year-old oceanic mystery

en Cerataspis and penaeoid shrimp, and more specifically the family Aristeidae, we sampled heavily within these groups," he said. The Crandall lab has been collecting crustacean DNA sequence data for a number of years and therefore had an excellent reference database to compare the Cerataspis DNA.

That's when analysis placed the larva and the deep-sea shrimp as one in the same.

"It's very exciting to have solved a nearly 200-year-old conundrum," said Dr. Crandall. "This was a project that involved having good luck with obtaining the sample, exceptional field knowledge to preserve the specimen and know that it was something special, outstanding state-of-the-art molecular and analytical tools to collect unique data that have only been available in the last 10 years to answer this question and to have an outstanding database of reference sequences to compare against."

The National Oceanic and Atmospheric Administration also supported some of the research by providing financial support for the ship time, ship, crew members and collection resources.

"Larval-adult linkages not only aid in our understanding of biodiversity, they provide insights into the life history, distribution and ecology of an organism," said Dr. Crandall.
