A healthy coral reef is a noisy place. “You’ve got this constant crackling sound. … That’s the sound of snapping shrimp,” says Steve Simpson of the University of Exeter in the United Kingdom. “Then on top of that, pops, grunts, growls, trumpeting sounds, whooping sounds … and these are generally made by fish that are […]
By Susan Cosier Come February in Wisconsin, almost everything will be covered in ice and snow. In little shanties on frozen Lake Winnebago, a 30-by-13-mile lake in the eastern part of the state, fishers will keep watch over rectangular holes cut into the ice with a chainsaw. When they spot a fin passing below, they’ll […]
By Jessica Corbett In a new report about how the world’s coral reefs face “the combined threats of climate change, pollution, and overfishing” — endangering the future of marine biodiversity — a London-based nonprofit calls for greater global efforts to end the climate crisis and ensure the survival of these vital underwater ecosystems. The report, […]
Scientists have identified four new species of walking shark in the waters off Australia and New Guinea. While that might sound like the stuff of horror films, researchers say that the foot-long fish, which have evolved to use their fins to walk on land or in shallow water, are actually adorable. “They’re incredibly cute little […]
Scientists have concluded of the largest freshwater fish species in the world is now extinct because of human activity. The Chinese paddlefish, sometimes called the “panda of the Yangtze River,” was found to have been lost to overfishing and habitat destruction, Phys.org reported Wednesday. Its extinction was announced and documented by researchers at the Chinese […]

Four dams — the Lower Granite, Little Goose, Lower Monumental and Ice Harbor — erected between 1955 and 1975, ease the way for massive barges bound for ports on […]
A photographer came across a strange sight when he walked along a Northern California beach last week: thousands of sausage-shaped, 10-inch worms stretching for miles down the beach. “I haven’t seen anything like that before,” David Ford, the photographer, told the Marin Independent Journal. So he wrote in to Bay Nature’s “Ask the Naturalist” column […]
The National Oceanic and Atmospheric Administration (NOAA) released its 14th annual Arctic Report Card Tuesday, and the results are grim. The average land temperature between October 2018 and August 2019 was the second-warmest on record since 1900, sea ice extent at the end of the summer was at its second lowest since satellite observations began […]
Human activity is smothering the ocean, the largest study of its kind has found, and it poses a major threat to marine life. The International Union for Conservation of Nature (IUCN) report combined the work of 67 scientists from 17 countries to conclude that oxygen levels in the ocean had declined around two percent since […]
