Missing fish catch data? Not necessarily a problem, new study says
Recording how many fish are caught is one important requirement to measure the well-being of a fish stock -- if scientists know the number of fish taken from the ocean, they can adjust management of that fishery to keep it from being overfished. Missing catch data, however, are rampant, causing concern that fisheries around the world are overfished. In many cases, misreporting caught fish doesn't always translate to overfishing, a new study finds.

Climate change will see some males get sexier
A common marine crustacean has shown researchers that it's all set to beat climate change -- the males will get more attractive to the females, with a resulting population explosion.

Powered for life: Self-charging tag tracks fish as long as they swim
A self-powered fish-tracking tag uses a flexible strip containing piezoelectric materials to emit tiny beeps that are recorded by underwater microphones. The device is designed for longer-living fish such as sturgeon, eels and lamprey.

Rising ocean temperatures threaten baby lobsters
If water temperatures in the Gulf of Maine rise a few degrees by end of the century, it could mean trouble for lobsters and the industry they support, according to newly published research.

Oxygen levels were key to early animal evolution, strongest evidence now shows
It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago.

Caspian terns discovered nesting 1,000 miles farther to the north than ever recorded in Alaska
In the late summer of 2016, a field team monitored Caspian tern chicks through to fledging in Cape Krusenstern National Monument in Alaska. This discovery of Caspian terns breeding above the Arctic Circle in the Chukchi Sea is nearly 1,000 miles farther north than previously recorded – a strikingly large jump in the range of nesting for this (or any) species.

Underwater 'Cystoseira zosteroides' forests, the Mediterranean algae, threatened by human activity impact
The effects of an intense storm every twenty-five years could make the marine alga populations of Cystoseira zosteroides disappear – an endemic species of the Mediterranean with great ecological value for the biodiversity of marine benthos – according to a new article.

Unique feeding habits of whales revealed
Whales are the biggest animals to ever have existed on Earth, and yet some subsist on creatures the size of a paper clip. It's a relatively common factoid, but, in truth, how they do this is only just being uncovered, thanks to new technologies.

New model could point way to microbiome forecasting in the ocean
A new mathematical model integrates environmental and molecular sequence information to better explain how microbial networks drive nutrient and energy cycling in marine ecosystems.

See it before it's gone: The paradox of 'last chance tourism' on the Great Barrier Reef
Many of the tourists now flocking to see Australia's Great Barrier Reef (GBR) are hoping to 'see it before it's gone' in the latest example of what's come to be known as 'Last Chance Tourism (LCT)'.

Marine life showing its true colors
Cephalopods -- cuttlefish, squid and octopus -- are renowned for their fast color changes and remarkable camouflage abilities. Now researchers have established that colorful coastal cephalopods are actually colorblind -- but can still manage to blend beautifully with their surroundings.

Ocean fronts attract ocean wanderers
Foraging seabirds use oceanic fronts as an efficient means to forage for food, according to an international study that could help safeguard the future of protected species.

Scientists triple known types of viruses in world’s oceans
Researchers report they've tripled the known types of viruses living in waters around the globe, and now have a better idea what role they play in nature. The discovery could influence carbon reduction efforts.

Antarctic mystery solved?
Tiny ocean fossils distributed widely across rock surfaces in the Transantarctic Mountains point to the potential for a substantial rise in global sea levels under conditions of continued global warming, according to a new study. The study indicates the massive East Antarctic Ice Sheet (EAIS) has a history of instability during ancient warm periods and could be vulnerable to significant retreat and partial collapse induced by future climate change.

Fish against monster worms
Eunice aphroditois, also known as the Bobbit worm, buries its long body deep in the sand, leaving only its powerful jaws protruding above the surface. It uses these to grab hold of unsuspecting prey and drag it down into its burrow within a fraction of a second. Biologists have taken a closer look at the gruesome hunter and its prey and noticed a fascinating behavioral pattern: prey fish defend themselves against the monstrous worm by attacking it with water jets and forcing it to retreat.

To understand the oceans' microbes, follow function, not form
A mathematician may have discovered a key to understanding the constantly changing distribution of microbial species in the world’s oceans—classify microorganisms by their biochemical function, rather than by their taxonomy.

Fate of turtles, tortoises affected more by habitat than temperature
Habitat degradation poses a greater risk to the survival of turtles and tortoises than rising global temperatures, according to new research. More than 60 per cent are listed as vulnerable, endangered, or critically endangered, because they are being traded, collected for food and medicine and their habitats are being degraded. Understanding the additional impact of global warming and changes in rainfall patterns on their diversity and distributions is therefore paramount to their conservation.

Sea otter survey encouraging, but comes up short of the 'perfect story'
The southern sea otter,Enhydra lutris nereis, continues its climb toward recovery, according to the annual count. For the first time, southern sea otters' numbers have exceeded the threshold required by the U.S. Fish and Wildlife Service to consider de-listing the species as "threatened" under the Endangered Species Act.

Heatwaves in the ocean: Risk to ecosystems?
Marine ecosystems are responsible for about half of global annual primary production and more than one billion people rely on fish as their primary protein source. Latest studies show that enormous warm water bubbles in the ocean are having a noticeable impact on ecosystems. How should we interpret these changes?
