Almost 4 decades later, mini eyeless catfish gets a name
Discovered in a 1978-79 expedition, a pale, eyeless catfish that doesn't even measure an inch long is now known as Micromyzon orinoco, for the South American river in which it was discovered.

The oldest fossilized giant penguin
A recently discovered fossil of a giant penguin with a body length of around 150 centimeters has been described in a new article. The new find dates back to the Paleocene era and, with an age of approximately 61 million years, counts among the oldest penguin fossils in the world. The bones differ significantly from those of other discoveries of the same age and indicate that the diversity of Paleocene penguins was higher than previously assumed. The team of scientists therefore postulates that the evolution of penguins started much earlier than previously thought, probably already during the age of dinosaurs.

Hot spots of marine biodiversity most severely impacted by global warming
A new study aimed at identifying areas of highest conservation priority in the world's oceans found six 'hot spots of marine biodiversity' that are severely impacted by climate change and fishing pressures.

Hidden no more: First-ever global view of transshipment in commercial fishing industry
A new report released today presents the first global map of transshipment, a major pathway for illegally caught and unreported fish to enter the seafood market. Also associated with drug smuggling and slave labor, it is Illegal in many cases, and has been largely invisible until now. Using an artificial intelligence system developed by Global Fishing Watch, data scientists have developed an automated process for identifying and tracking transshipment around the world.

Cutting-edge cameras reveal the secret life of dolphins
Dolphins have been recorded in rarely-seen activities of mother-calf interaction, playing with kelp, and intimate social behaviors like flipper-rubbing through the use of largely non-invasive new cameras.

Professor examines effects of climate change on coral reefs, shellfish
Professor is studying how a variety of marine organisms are responding to changes in their environment. Focusing on reef-building corals and other shelled creatures that are threatened by increasing temperatures and ocean acidification, she is testing them to determine how species may acclimatize to the new circumstances.

Impacts of mass coral die-off on Indian Ocean reefs revealed
Warming seawaters, caused by climate change and extreme climatic events, threaten the stability of tropical coral reefs, with potentially devastating implications for many reef species and the human communities that reefs support.

More warm-dwelling animals and plants as a result of climate change
Since 1980, populations of warm-dwelling species in Germany have increased. The trend is particularly strong among warm-dwelling terrestrial species, as shown by the most comprehensive study across ecosystems in this regard to date. The most obvious increases occurred among warm-dwelling birds, butterflies, beetles, soil organisms and lichens according to a new study. Thus, it appears possible that rising temperatures due to the climate change have had a widespread impact on the population trends of animals in the past 30 years.

Basking sharks seek out winter sun
The winter habits of Britain's basking sharks have been revealed for the first time. Scientists have discovered some spend their winters off Portugal and North Africa, some head to the Bay of Biscay and others choose a staycation around the UK and Ireland.

Congo River fish evolution shaped by intense rapids
New research provides compelling evidence that a group of strange-looking fish living near the mouth of the Congo River are evolving due to the intense hydraulics of the river's rapids and deep canyons. The study reveals that fishes in this part of the river live in 'neighborhoods' that are separated from one another by the waters' turbulent flow.

Underwater seagrass beds dial back polluted seawater
Seagrass meadows -- bountiful underwater gardens that nestle close to shore and are the most common coastal ecosystem on Earth -- can reduce bacterial exposure for corals, other sea creatures and humans, according to new research.

Scientists find evidence of Alaskan ecosystem health in Harlequin ducks
Harlequin Ducks in coastal areas of Alaska’s Kodiak and Unalaska islands are exposed to environmental sources of mercury and that mercury concentrations in their blood are associated with their local food source, mainly blue mussels, research shows.

Biodiversity can promote ecosystem efficiency
Humans influence evolution. In the case of whitefish in Swiss lakes, one consequence of this is replacement of a diversity of specialized species by fewer generalists. A recent analysis now suggests that communities of diverse specialists utilize trophic resources more efficiently.

90 percent of fish used for fishmeal are prime fish
From 1950 to 2010, 27 percent of commercial marine landings were diverted to uses other than direct human consumption, a new research project has found.

Extreme fluctuations in forage fish populations
California sardine stocks famously crashed in John Steinbeck's 'Cannery Row.' New research, building on the pioneering work of Soutar and Isaacs in the late 1960s and others, shows in greater detail that such forage fish stocks have undergone boom-bust cycles for centuries, with at least three species off the US West Coast repeatedly experiencing steep population increases followed by declines long before commercial fishing began.

Whale-ship collisions
Scientists and government officials met at the United Nations today to consider possible solutions to a global problem: how to protect whale species in their most important marine habitats that overlap with shipping lanes vital to the economies of many of the world's nations.
