A species of damselfish, Stegastes nigricans, selectively weed the algal gardens on which they feed in order to encourage the growth of their preferred algal species of Polysiphonia and suppress the growth of less palatable algae. Researchers writing in the open access journal BMC Evolutionary Biology investigate the feeding preferences of damselfish and explore their diverse gardening systems across the Indo-West Pacific region. Hiroki Hata from Ehime University, Japan, worked with a team of...

Damselfish are killing head corals and adding stress to Caribbean coral reefs, which are already in desperately poor condition from global climate change, coral diseases, hurricanes, pollution, and overfishing. Restoring threatened staghorn coral, the damsels' favorite homestead, will take the pressure off the other corals, according to a new study published in the online journal PLoS ONE. The small, belligerently territorial, threespot damselfish kill portions of coral colonies to grow...

In a remarkable new finding scientists from The Vision Centre have reported that certain coral reef fish use ultraviolet (UV) vision to tell the difference between their own and other similar species. Indeed, the otherwise rather plain-looking Ambon damselfish may even be able to recognize individuals by their faces, in much the same way as humans do, the researchers say in a paper in the latest issue of the journal Current Biology. The UV vision may act as a secret channel of communication...

Two species of damselfish may look identical"”not to mention drab"”to the human eye. But that's because, in comparison to the fish, all of us are essentially colorblind. A new study published online on February 25th in Current Biology, a Cell Press publication, reveals that the fish can easily tell one species from another based entirely on the shape of the ultraviolet (UV) patterns on their faces. Although scientists have long known that some animals have UV vision, the new...
