Reef fish evolved the ability to feed by biting prey from surfaces relatively recently, a UC Davis study shows. The innovation has driven an explosion of evolution in reef fish. Image shows a rainbow ...

Along the murky bottom of the Amazon River, serpentine fish called electric eels scour the gloom for unwary frogs or other small prey. When one swims by, the fish unleash two 600-volt pulses of ...

Theories of evolution were developed without an understanding of genetics, and while our ability to study genes has advanced tremendously, those advancements have happened only in the past few decades ...

AbstractDiadromous species undergo regular migration between fresh and marine waters. This behavior is found in many species, including fish, mollusks, and crustaceans, some of which are commercially ...

When an Australian scientist uncovered an ancient-looking placoderm skull in the 1960s, he thought he'd cracked the code on an evolutionary mystery. This so-called 'platypus fish,' scientists had ...

Evolution is usually viewed as a slow process, with changes in traits emerging over thousands of generations only. Over the recent years, however, research has indicated that adaptation in specific ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. The previously unknown Xingren golden-line fish appears to be still evolving for cave life. . | ...

To escape predators beneath the waves, a flying fish can shoot out of the water and glide long distances because its paired pectoral and pelvic fins, longer and more rigid than those of other fish, ...

Genetic analysis of sticklebacks shows that isolated populations in similar environments develop in comparable ways. The basis for this is already present in the genome of their genetic ancestors.

Researchers have identified the genetic basis of rapid adaptation using a native fish species. They compared threespine stickleback fish from different habitats in the Lake Constance region. Their ...
