Smithsonian scientists discover 7 new species of fish
Date:2/4/2011

Things are not always what they seem when it comes to fishsomething scientists at the Smithsonian Institution and the Ocean Science Foundation are finding out. Using modern genetic analysis, combined with traditional examination of morphology, the scientists discovered that what were once thought to be three species of blenny in the genus Starksia are actually 10 distinct species. The team's findings are published in the scientific journal ZooKeys, Feb. 3.

Starksia blennies, small (less than 2 inches) fish with elongated bodies, generally native to shallow to moderately deep rock and coral reefs in the western Atlantic and eastern Pacific oceans, have been well-studied for more than 100 years. It would have been reasonable to assume that there was little about the group left to discover. Modern DNA barcoding techniques, however, suggested otherwise. While trying to match larval stages of coral reef fish to adults through DNA, the team of scientists noticed contradictions between the preliminary genetic data and the current species classification. Further investigation revealed that the team was dealing with many species new to science, including the new Starksia blennies.

"DNA analysis has offered science a great new resource to examine old questions," said Carole Baldwin, a zoologist at Smithsonian's National Museum of Natural History and lead author of the paper. "This discovery is a perfect example of how DNA barcoding is illuminating species that we've missed before, particularly small cryptic reef fishes like Starksia blennies. We don't know where we stand in terms of understanding species diversity, and our work suggests that current concepts may be surprisingly incomplete."

But DNA analysis cannot stand on its ownBaldwin and her team only recognize genetic lineages as species if they are supported by morphology. So traditional morphological analysis, such as comparing patterns of pigmentation
