Changing ocean hues could bring some environmental blues, according to a new study from researchers at Duke and Georgia Tech.

Diet. Just like flamingos get their pink color from a shrimp-heavy diet, and redfish get their trademark tail spots from eating blue crabs, a trout’s diet can have a real impact on its coloration.

In nature, it's not uncommon to observe animals that change color with the seasons. You may have heard of the arctic fox or the mountain hare, which are white in winter and brown in summer.

Their analysis confirms that the predatory fish rapidly change color, suggesting that the color change might serve as a reliable signal of an individual’s motivation to go in for an attack.

Researchers developed a way to run tests on fish learning and memory in the animals' natural environments. The results may reveal that fish are smarter than previously assumed.

Their coloration ranges from deep blacks to vibrant oranges, and their dorsal, ventral and tail fins are colored differently as well. "Any of these different color attributes could be used by the ...

The experiment in question involved 120 individual A. ocellaris fish, which typically have three white bars on their bodies. The fish were then provided with opportunities to interact with model ...

Anemonefishes are a group of damselfishes “that exclusively live symbiotically with sea anemones,” researchers said in a July 10 study published in the peer-reviewed journal ZooKeys. They are ...
