What It Feels Like To Be the Target of China’s Water Cannons

The Filipino fishers on wooden boats waved at our vessel, a Philippine fisheries boat, from less than a mile away, but no one on our ship dared to move. Encircling us were two Chinese Coast Guard ships and five Chinese militia vessels. Then came the water cannon. One of the Chinese Coast Guard ships had fired the high-intensity water jet at our boat to prevent us from getting closer to fishermen near the Scarborough Shoal, a triangular chain of reefs and rocks 140 miles west of the Philippines. The blast…

Fossilized Fish Reveal Earliest Known Prequel of ‘Jaws’

Mention the ocean, and it’s hard not to think of jaws. The deep waters contain many tooth-lined mouths: the bear-trap maws of sharks and dolphins, the slack lips of shoaling and reef fish, the baleen-filter gape of enormous whales. Jawed fish eventually crawled out of the seas millions of years ago and gave rise to the jawboning vertebrates we are today. But when did such an evolutionary innovation arise? A pair of fossil beds discovered in Southern China suggest that the answer may lie tens of millions of years deeper…

‘Penis Worms’ May Have Been the First Hermits

Consider this evolutionary dilemma, faced by the aquatic and squishy: How do you survive in hostile, predator-filled oceans? Squid rely on speed or camouflage. Snails develop complex shells. Hermit crabs borrow those complex shells when other animals aren’t using them, trading them out for bigger models as they grow. This sheltering strategy was believed to have emerged 180 million years ago in the Jurassic Period, when hermit crabs’ ancestors appeared in oceans, said Martin Smith, a paleontologist at the University of Durham in England. But in a study published Monday…
