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 ...

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 ...

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 ...

Learn how a small genetic change affects cell communication and reshapes the stripes seen in clownfish.

Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and ...

A midbrain region in fish combines light signals from the eyes and the pineal organ, a light-sensing structure often called the 'third eye.' ...

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 ...

How the leopard got its spots and the zebra its stripes might not be just-so stories much longer. Biologists are beginning to pinpoint the molecular mechanisms animals use to deck themselves out with ...

Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive. Now engineers at CU ...
