Survival of the fittest: Ocean acidification produces winners and losers
(Phys.org)—As atmospheric carbon dioxide levels continue to increase, the ocean absorbs more carbon dioxide. This absorption comes at a cost, since it makes the ocean more acidic. An acid ocean will affect ...
Earliest sea cow ancestors originated in Africa, lived in fresh water
A new fossil discovered in Tunisia represents the oldest known ancestor of modern-day sea cows, supporting the African origins of these marine mammals. The find is described in research published January 16 in the open access ...
New Antarctic geological timeline aids future sea-level predictions
Radiocarbon dates of tiny fossilised marine animals found in Antarctica's seabed sediments offer new clues about the recent rapid ice loss from the West Antarctic Ice Sheet and help scientists make better predictions about ...
Breeding season under way for Galapagos tortoises
Breeding season is under way for the endangered tortoises of Ecuador's Galapagos Islands, whose mating and nesting habits are carefully watched by wildlife specialists hoping to save them from extinction.
Whales' foraging strategies revealed by new technology

Ups and downs of biodiversity after mass extinction
The climate after the largest mass extinction so far 252 million years ago was cool, later very warm and then cool again. Thanks to the cooler temperatures, the diversity of marine fauna ballooned, as paleontologists ...
Scientific divers discover 36,000-year-old Atlantic gray whale fossil
(Phys.org)—While the Atlantic gray whale was hunted to extinction by the 1700s, the Pacific or California gray swims today with a population near its pre-whaling levels. University of Georgia scientists ...
Study reveals that animals contribute to seagrass dispersal
Look out the window and you're likely to see the dispersal of seeds—dandelion tufts in the wind, a squirrel burying an acorn, a robin flying off with a dogwood fruit. You might even have a burr "velcroed" ...
'Sense-ational' invention helps underwater vessels navigate with ease
Nanyang Technological University (NTU) scientists have invented a 'sense-ational' device, similar to a string of 'feelers' found on the bodies of the Blind Cave Fish, which enables the fish to sense their ...
New to science: Find from 425 million years ago with body, limbs, eyes, gills and alimentary system preserved
An international team of researchers have made an extremely rare discovery of a species of animal - related to crabs, lobsters and shrimps – that is new to science.
Reducing underwater noise to help health of marine wildlife
(Phys.org)—Research by scientists at the University of Bath is being used to help inform new EU legislation on levels of underwater noise, with the aim of reducing the impact of noise pollution on marine wildlife.
