Sea turtles face plastic pollution peril
A new global review that set out to investigate the hazards of marine plastic pollution has warned that all seven species of marine turtles can ingest or become entangled in the discarded debris that currently litters the oceans.

A long look back at fishes' extendable jaws
When it comes to catching elusive prey, many fishes rely on a special trick: protruding jaws that quickly extend their reach to snap up that next meal. Now, researchers have found a clever way to trace the evolution of jaw protrusion in fishes over many millions of years.

NOAA declares third ever global coral bleaching event
As record ocean temperatures cause widespread coral bleaching across Hawaii, scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.

Self-regulating corals protect their skeletons against ocean acidification
Scientists have found a species of coral living in a dynamic reef system, which is able to protect itself from the impact of ocean acidification. Ocean acidification, caused by rising carbon dioxide, is one of the greatest long-term challenges facing reefs. It reduces coral's ability to form their skeletons and build reef structures.

New fossils intensify mystery of short-lived, toothy mammal found in ancient North Pacific
New fossils from the Aleutian Islands intensify the mystery surrounding a toothy, hippopotamus-sized mammal unique to the North Pacific. The oddball creature suction-fed shoreline vegetation, say paleontologists. The Unalaska Island animal is a new genus and species of Desmostylia. The only major order of marine mammals to go wholly extinct, Desmostylia survived a geologic blink -- only 23 million years, from 33 million to 10 million years ago.

The predator survives – but the ecosystem crashes
What do killer whales, polar bears and humans have in common? They are adaptable predators with the ability to select new prey when their favourite food is in low supply. But this change can disrupt entire ecosystems.

Bacteria in the world’s oceans produce millions of tons of hydrocarbons each year
Scientists have calculated that millions of tons of hydrocarbons are produced annually by photosynthetic bacteria in the world's oceans.

Are fish the greatest athletes on the planet?
Fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species, researchers have discovered.

To breathe or to eat: Blue whales forage efficiently to maintain massive body size
As the largest animals to have ever lived on Earth, blue whales maintain their enormous body size through efficient foraging strategies that optimize the energy they gain from the krill they eat, while also conserving oxygen when diving and holding their breath, a new study has found.

Researchers design 'biological flashlight' using light-producing ability of shrimp
Researchers describe the design and engineering of the new bioluminescent imaging tool called the “LumiFluor” in a new report. Using the natural light-producing ability of deep-sea shrimp, the team of scientists developed the new imaging tool to help cancer researchers better track tumor development and treatment responses.

Researchers in Northwestern Hawaiian Islands finds highest rates of unique marine species
Scientists returned from a 28-day research expedition aboard NOAA Ship Hi'ialakai exploring the deep coral reefs within Papahanaumokuakea Marine National Monument in the Northwestern Hawaiian Islands. During the trip, scientists recorded numerous species of marine life never before seen, including a possible new species of seahorse, and a sea star not previously found in Hawaii.

A balanced diet is good for corals too, study finds
A nutrient-rich, balanced diet is beneficial to corals during stressful thermal events, new research shows. The study concluded that the particular nutrient balance in seawater is what matters most.

Sensory feedback shapes individuality to provide equal space for behavioral excellence
Variability, such as that seen in movement, is essential both for normal behavior and for longer-term evolution, scientists suggest. Their animal study shows sensory feedback increases the range of responses -- variability -- within individuals, but decreases the range across a group.

Many young fish moving north with adults as climate changes
Numerous studies in the Northeast US have shown that adult marine fish distributions are changing, but few studies have looked at the early life stages of those adult fish to see what is happening to them over time. A new study has some answers, finding that distributions of young stages and the timing of the life cycle of many fish species are also changing.

Accurate timing of migration prolongs life expectancy in pike
Animal migration is a spectacular phenomenon that has fascinated humans for long. It is widely assumed that appropriate timing of migratory events is crucial for survival, but the causes and consequences of individual variation in timing are poorly understood. New research based on migrating pike in the Baltic Sea reveals how behaviors such as punctuality, flexibility and fine-tuning influence life expectancy in fish.

Known fish species living in the Salish Sea increases in new report
A new report documents all of the fishes that live in the Salish Sea. In total, 253 fish species have been recorded, and that’s about 14 percent more than in the last count.

Portable device can quickly test for sickness-causing toxins in shellfish
Mussels, oysters, scallops and clams might be ingredients for fine cuisine, but they can also be a recipe for diarrhetic shellfish poisoning (DSP). That's a gastrointestinal illness people can get if those tasty morsels contain marine toxins. Now, researchers are reporting the development of a portable, inexpensive device that can quickly and easily screen freshly caught shellfish for these substances.

Rare early Jurassic corals of North America
Mass extinction events punctuate the evolution of marine environments, and recovery biotas paved the way for major biotic changes. Understanding the responses of marine organisms in the post-extinction recovery phase is paramount to gaining insight into the dynamics of these changes, many of which brought sweeping biotic reorganizations.

King crabs threaten Antarctic ecosystem due to warming ocean
King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven't played a role in tens of millions of years, according to a new study.

Novel tag developed for squid, jellyfish
Invertebrates, such as squid and jellyfish, play a crucial role in the marine food web and are also vital commercial fisheries. Despite their importance, little is known about their natural behaviors or how their environment influences those behaviors or physiology.
