The genetic underpinnings of pigmentation and colour patterning in fish encompass a complex interplay of gene regulation, cell fate determination and evolutionary innovation. Neural crest cells, which ...

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 ...
