There’s a deeper fish in the sea
The ocean’s deepest fish doesn’t look like it could survive in harsh conditions thousands of feet below the surface. Instead of giant teeth and a menacing frame, the fishes that roam in the deepest parts of the ocean are small, translucent, bereft of scales — and highly adept at living where few other organisms can….

When to fish: Timing matters for fish that migrate to reproduce
A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.

Old fish few and far between under fishing pressure
A new study by University of Washington scientists has found that, for dozens of fish populations around the globe, old fish are greatly depleted — mainly because of fishing pressure. The paper, published online Sept. 14 in Current Biology, is the first to report that old fish are missing in many populations around the world.

Climate change challenges the survival of fish across the world
Climate change will force many amphibians, mammals and birds to move to cooler areas outside their normal ranges, provided they can find space and a clear trajectory among our urban developments and growing cities. But what are the chances for fish to survive as climate change continues to warm waters around the world? University…

Scientists to create digital encyclopedia of 3-D vertebrate specimens
A $2.5 million National Science Foundation grant will daylight thousands of specimens from their museum shelves by CT scanning 20,000 vertebrates and making these data-rich, 3-D images available online to researchers, educators, students and the public. The University of Washington is a partner institution contributing most of the fish and bat scans.

Native American youth launch high-altitude balloons for unique perspective on solar eclipse
While many people across the country donned viewing glasses and prepared to watch Monday’s solar eclipse, a group of 100 teenagers from tribes across the Pacific Northwest launched balloons thousands of feet into the air, gaining a novel perspective of the eclipse — and the chance to send meaningful artifacts to the edge of space during a memorable moment in history.
