Animal with the most genes? A tiny crustacean
Date:2/3/2011

BLOOMINGTON, Ind. -- Complexity ever in the eye of its beholders, the animal with the most genes -- about 31,000 -- is the near-microscopic freshwater crustacean Daphnia pulex, or water flea. By comparison, humans have about 23,000 genes. Daphnia is the first crustacean to have its genome sequenced.

The findings are part of a comprehensive report in this week's Science by members of the Daphnia Genomics Consortium, an international network of scientists led by the Center for Genomics and Bioinformatics (CGB) at Indiana University Bloomington and the U.S. Department of Energy's Joint Genome Institute. A bullet-point list of the Science paper's most important findings appears at the end of this release.

"Daphnia's high gene number is largely because its genes are multiplying, by creating copies at a higher rate than other species," said project leader and CGB genomics director John Colbourne. "We estimate a rate that is three times greater than those of other invertebrates and 30 percent greater than that of humans."

Daphnia Genomics Consortium projects can be found at http://daphnia.cgb.indiana.edu, as well as a link to the nearly 40 companion papers based on the data reported in the Science paper.

Scientists have studied Daphnia for centuries because of its importance in aquatic food webs and for its transformational responses to environmental stress. Predators signal some of the animals to produce exaggerated spines, neck-teeth or helmets in self-defense. And like the virgin nymph of Greek mythology that shares its name, Daphnia thrives in the absence of males -- by clonal reproduction, until harsh environmental conditions favor the benefits of sex.

Daphnia's genome is no ordinary genome.

"More than one-third of Daphnia's genes are undocumented in any other organism -- in other words, the
