Earth Holds 8.7M Species, Study Finds

And most of them are still undiscovered

(Newser) - Humanity shares the planet with roughly 8.7 million species, most of them still undiscovered, according to a new study.

Why Seahorses Are So Curvy

Scientists say odd shape makes them better hunters

(Newser) - The seahorse is one of the more unusual-looking creatures in the oceans, and now scientists say they've unlocked the secret to the curvy shape—it's all about hunting.

Gulf Oil Spill Fallout Baffles Scientists

Scientists have little experience with oil from below

(Newser) - The Gulf oil spill will affect all living things in the area—but determining what those consequences will be is stumping the best minds in environmental science. There's never been an oil spill of the magnitude of the Deepwater Horizon accident on the ocean floor, and data is scarce on...

Monster Squid Turns Out to Be Lazy Blob

Legendary predator just waits for prey to swim by

Life Found Deep Beneath Antarctic Ice

Sophisticated creatures found 600ft below frozen sheet

(Newser) - NASA scientists probing 600 feet beneath an Antarctic ice sheet were amazed to find sophisticated life where they had expected to find a few microbes at best. The team put a video camera into the dark subfreezing water and found a shrimp-like creature clinging to the cable when they pulled...

Coconut-Carrying Octopus Stuns Scientists

Homebuilding is first time tool use has been seen among octopi

(Newser) - Australian scientists observing octopi on the sea floor near Indonesia were amazed to discover that the creatures scoop up coconut halves, empty them out, and carry them around to assemble into shelters. The behavior shows a surprising level of intelligence, the researchers say, and is the first recorded instance of...

20-foot creature is the first giant squid ever netted by Gulf researchers

(Newser) - Scientists studying whale diets in the Gulf of Mexico unexpectedly hauled in a giant squid half as long as a school bus, Reuters reports. The 19.5-foot-long creature dragged up from 1,500 feet below the sea off Louisiana is the first giant squid found in the area in over...

New England Starfish Boom Baffles Experts

Shellfish predators' population worries fishermen

(Newser) - New England beaches are swarming with starfish this spring, and nobody’s sure why, the Boston Globe reports. The spike may be connected to shellfish population; it could be due to a drop in spider crabs, which prey on starfish; it could be tied to water temperature or wind patterns....

Climate Change May Tank World's Fish Stocks

Scientists predict huge upheaval to marine populations

(Newser) - The world's supplies of fish face major upheaval, scientists warn, as climate change forces species from shrimp to herring away from warming waters toward the poles. The BBC reports that in 40 years, American fishermen may see a 50% reduction in the population of Atlantic cod. "The impact of...

Fishing Banned in Melting Arctic

Federal panel moves to block trawlers from newly accessible waters

(Newser) - A federal panel has voted to block fishing trawlers from moving into a vast area of the Arctic Sea made newly accessible by melting ice, the New York Times reports. The move will protect 150,000 square nautical miles of US waters north of the Bering Strait while scientists assess...

To Find the Killer Whale, Scientists Think Like One

Off of Scotland, team stakes out its prey

(Newser) - Killer whales spend most of their time tracking their prey, and so do the scientists who study them. Marine biologists at Scotland's St. Andrews University spent 3 months among the Shetland Islands in search of their cetacean quarry, and caught sight of whales only about 12 times. They explain to...

Dolphins' Hunting Tools Mostly Used by Females

Dolphin moms pass skills on to daughters; males do their own thing

(Newser) - Beside humans, few other animals use tools to get their everyday chores done. Even fewer of them are marine mammals, so researchers in Australia were surprised to catch bottlenose dolphins employing conical sponges to dig in the seafloor. Mostly female dolphins use the snout-protectors, and only if their mothers showed...
