These fish turn up in many surprising locations, but this was one place scientists didn’t expect to find them. By Veronique Greenwood Killifish manage to endure a variety of environments. The wee ...

Gulf killifish embryos exposed to sediments from oiled locations show developmental abnormalities, including heart defects, delayed hatching and reduced hatching success. Crude oil toxicity continued ...

For most of the year, annual killifish persist as diapausing embryos buried in sediments across the African savannah. When rainwater fills small depressions across the landscape, the fish must hatch, ...

Ranging in size from about 2 to 6 inches, the killifish are ideal for evolutionary studies because they are highly adaptable to their surroundings. Some types of killifish are even known to be ...

Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research from The University of Texas at Arlington. It has long been ...

FREDERICK, Md. (AP) -- Just add water. That's all it takes to hatch fish embryos in a kit developed by the Fort Detrick-based U.S. Army Center for Environmental Health Research to help test for water ...

Killifish biology has long intrigued fish enthusiasts and scientists. But human encroachment, habitat loss and climate change are dwindling killifish populations in the wild. Thankfully, collection ...

Tokyo police on March 8 arrested five men on suspicion of illegally breeding and selling killifish that were genetically modified to make them “red and shiny.” Genetically modified organisms can ...

Aug. 6 (UPI) --New research suggests no vertebrate species matures as quickly as Africa's turquoise killifish. The tiny fish persist for most of the year as diapausing embryos buried in savannah ...

Fish embryos exposed to oiled sediment in a laboratory setting, even when the oil isn’t visible, take longer to hatch and those that do hatch have deformities like elongated hearts, according to an ...

Annual killifish are known to live their lives at one of two speeds: "pause" or "fast-forward." For most of the year, the tiny freshwater fish persist as diapausing embryos buried in sediments across ...
