A team of researchers has provided the first example of how color patterns on a coral reef fish species can drive its evolution into many distinct species. The researchers looked at feeding and mating ...

Visual signals, such as color patterns are an important communication medium for anemonefish. Researchers from Okinawa Institute of Science and Technology have recently elucidated how the patterns on ...

Similarities in how different organisms look can indicate a close evolutionary relationship. Conversely, great differences in appearance can suggest a very distant relationship, as in many adult ...

Deep-diving fish have a problem: The only light that penetrates their watery environment is blue and green — hardly enough of a palette for flashy color patterns. Now, a new study reveals these fishes ...

A fisherman in Minnesota has caught a sunfish with a rare genetic mutation that makes its skin golden. Terry Nelson was fishing for sunfish and crappies on Lindstrom Lake, in Chisago County, when he ...

Understanding Fish Coloration Fish colors are produced through specialized cells called chromatophores. These cells contain ...
