Fish can recognize a face based on UV pattern alone (3/4/2010)

Fish can recognize a face based on UV pattern aloneTwo 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 Feb. 25 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 patterns on their faces. ...> Full Article



Fish vision discovery makes waves in natural selection (10/20/2009)

Fish vision discovery makes waves in natural selectionEmory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. ...> Full Article


German researchers find there is more to bats' vision than meets the eye (7/31/2009)

The eyes of nocturnal bats possess two spectral cone photoreceptor types for daylight and color vision. Reporting in the open-access, peer-reviewed journal PLoS ONE, July 28, scientists at the Max Planck Institute for Brain Research in Frankfurt and the University of Oldenburg have detected cones and their visual pigments in two flower-visiting species of bat. ...> Full Article



An 'eye catching' vision discovery (7/28/2009)

An 'eye catching' vision discoveryNearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine have discovered in fish yet another type of cell that can sense light and contribute to vision. ...> Full Article

Mantis shrimp vision reveals new way that animals can see (3/24/2008)

Mantis shrimp vision reveals new way that animals can seeMantis shrimp can see the world in a way that had never been observed in any animal before, researchers report in the March 20th Current Biology, a Cell Press publication. The discovery-which marks the fourth type of visual system-suggests that the ability to perceive circular polarized light may lend mantis shrimp a secret mode of communication. ...> Full Article
