    National Geographic featured a story presented at the Behaviour conference in Cairns August 2015, this led a feature by the Canadian Discovery channel.

    A school of fish might seem like a sea of identical faces, but at least one species has no problem telling its comrades—and even strangers—apart, new research says.
    To human eyes, which cannot see ultraviolet light, the Ambon damselfish (Pomacentrus amboinensis), appears yellow with a few spots. But to damselfish, which can see ultraviolet wavelengths, their fellow species sport a complex array of facial patterns that are unique to each individual.

    Split division How Archerfish decide

    Article on wired.com featuring the Newport et al. paper on Archerfish decision making.

    When testing the discrimination abilities of an animal, the researcher usually depends upon the animal subjects to make a certain response to indicate their choice. Monkeys can push buttons or move joysticks, pigeons can peck at different keys, rats can press levers. Compared to these common laboratory animals, the behavioral repertoires of most fish might seem limited. But there is one fish that has a unique and reliable method for indicating its response in behavioral tests: the archerfish. The archerfish is a champion spitter. In the wild, they spit well-aimed jets of water to knock insects off vegetation above the water.

    Fish Use UV Patterns to Tell Species Apart

    Science | Nature Research Highlight (Nature 464, 10, doi: 10.1038/464010a)

    If you’ve seen one damselfish, you’ve seen them all. That may be true for people, who have a difficult time telling some damselfish species apart. But the fish themselves see it differently, according to a study in Current Biology. They can use ultraviolet facial patterns to tell one species from another. Ulrike E. Siebeck of the University of Queensland in Australia and colleagues studied Pomacentrus amboinensis and P. moluccensis, two species of damselfish capable of seeing light at the ultraviolet end of the spectrum. They are also highly territorial: P. amboinensis males, for example, will chase off unfamiliar members of their species because they are seen as competitors, but go easier on P. moluccensis intruders.

    For Fish in Coral Reefs, It’s Useful to Be Smart

    New York Times Science feature article

    I have long suspected that fish are smarter than we give them credit for. As a child, I had an aquarium with several pet goldfish. They certainly knew it was feeding time when my hand appeared over their tank, and they excitedly awaited their delicious fish flakes. They also exhibited a darker, disturbing behavior. Evidently, a safe life with abundant food was not fulfilling. From time to time, either sheer ennui or the long gray Toledo winter got to one of the fish and it ended its torment with a leap to my bedroom floor. Maybe my anthropomorphizing is a bit over the top. But, really, just how smart are fish? Can they learn?
