New Deep-Sea Worm Discovered at Methane Seep off Costa Rica
University of California San Diego

Greg Rouse, a marine biologist at UC San Diego’s Scripps Institution of Oceanography, and other researchers have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica. Rouse, curator of the Scripps Benthic Invertebrate Collection, co-authored a study describing the new species in the journal PLOS ONE that was published on March 6.

Counting Rays: Aerial Surveys Reveal Ample Populations in Southeast Florida
Florida Atlantic University

A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/ Miami.

Walleye struggle with changes to timing of spring thaw
University of Wisconsin–Madison

Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada.According to a new study published Feb. 26 in the journal Limnology and Oceanography Letters, part of the problem is that walleye are creatures of habit, and the seasons — especially winter — are changing so fast that this iconic species of freshwater fish can’t keep up.

In a first-of-its-kind study, researchers at the Georgia Institute of Technology discovered that sea cucumbers — sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor — play an enormous role in protecting coral from disease. The problem is, they've been overharvested for more than 100 years, and they're now rare.

Like Indiana Jones, thresher sharks have mastered the art of the whip using their tails. Now, new research provides intricate details showing that vertebrae anatomy might support the mechanics of extreme body bending in thresher sharks, enabling these expert hunters to weaponize their tails.
