Mucus may play vital role in dolphin echolocation
A dolphin chasing a tasty fish will produce a stream of rapid-fire echolocation clicks that help it track the speed, direction and distance to its prey. Now researchers have developed a model that could yield new insights into how the charismatic marine mammals make these clicks - and it turns out mucus may play an important role.

Northern invaders threaten Antarctic marine life
Scientists have found evidence that marine life can easily invade Antarctic waters from the north, and could be poised to colonize the rapidly-warming Antarctic marine ecosystems.

Coral bleaching 'lifeboat' could be just beneath the surface
A report commissioned by the United Nations offers a glimmer of hope to those managing the impact of bleaching on the world's coral reefs, including the Great Barrier Reef. The 35 authors of the United Nations Environmental Programme in-depth report say as the world's surface reefs are being threatened, part of the ecosystem may survive in these barely known deeper environments, known as mesophotic coral ecosystems (MCEs).

World's largest coral gene database created
Scientists have conducted the world's most comprehensive analysis of coral genes, focusing on how their evolution has allowed corals to interact with and adapt to the environment.

In changing oceans, cephalopods are booming
Humans have changed the world's oceans in ways that have been devastating to many marine species. But, according to new evidence, it appears that the change has so far been good for cephalopods, the group including octopuses, cuttlefish, and squid. The study shows that cephalopods' numbers have increased significantly over the last six decades.

Nanoplastics negatively affect aquatic animals
Plastic accounts for nearly eighty per cent of all waste found in our oceans, gradually breaking down into smaller and smaller particles. New research investigates how nanosized plastic particles affect aquatic animals in different parts of the food chain.

Strange sea-dwelling reptile fossil hints at rapid evolution after mass extinction
For a long time, scientists believed that the early marine reptiles that came about after the great Permian-Triassic mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question. The newly described Sclerocormus parviceps is a marine reptile called an ichthyosauriform, and its strange features (short snout, long, whip-like tail) are really different from many of its relatives, revealing that marine reptiles evolved and diversified after the extinction more quickly than previously thought.

Lingcod meet rockfish: Catching one improves chances for the other
Researchers found that selectively fishing for lingcod in protected areas actually avoided hampering the recovery of other fish, including rockfish species listed as overfished.

'Canaries' of the ocean highlight threat to world's ecosystems
A new study highlights the urgent need for action to save our coral reefs as 59 species of finfish disappear from catches over past 65 years.

Rich coral communities discovered in Palamós Submarine Canyon in the Northwestern Mediterranian Sea
A scientific team has found in La Fonera canyon, also known as the Palamós canyon in the Northwestern Mediterranian Sea, deep-water coral communities, a marine ecosystem which is very vulnerable to human activity.

Ocean acidification puts NW Dungeness crab at risk
Ocean acidification expected to accompany climate change may slow development and reduce survival of the larval stages of Dungeness crab, a key component of the Northwest marine ecosystem and the largest fishery by revenue on the West Coast, a new study has found.

Fish can adapt some to warmer ocean waters, but not necessarily to extreme heat
A three-decade-old open air laboratory, where warm water from a nuclear power station is pumped into an enclosed basin in the Baltic Sea off the Swedish coast, gives researchers an unparalleled chance to study how warmer waters and higher temperature extremes affect fish. While fish were able to adjust their metabolic rates to cope with the heat, they had less of a cushion with respect to extreme temperatures.

Biodiversity protects fish from climate change
Fish provide protein to billions of people and are an especially critical food source in the developing world. Today marine biologists confirmed a key factor that could help them thrive through the coming decades: biodiversity. Communities with more fish species are more productive and more resilient to rising temperatures and temperature swings, according to a new study.

More sea turtles survive with less beach debris
Clearing the beach of flotsam and jetsam increased the number of nests by as much as 200 percent, while leaving the detritus decreased the number by nearly 50 percent, report scientists at the conclusion of their study.

Tiny organisms have huge effect on world’s atmosphere
Scientists have discovered how a tiny yet abundant ocean organism helps regulate Earth's climate. They showed that these tiny, hugely abundant bacteria could make the environmentally important gas, dimethyl sulfide.

Coal shipping threat to Great Barrier Reef
Australian researchers have raised fresh concerns that a major shipping disaster could harm the Great Barrier Reef, with new research revealing coal dust in seawater can kill corals and slow down the growth rate of seagrasses and fish.

World’s smallest porpoise nears extinction
Mexican authorities are being called on to immediately and indefinitely close all fisheries within the habitat of Mexico's critically endangered vaquita porpoise. Only around 60 vaquitas remained in the upper Gulf of California -- the only place the species exists -- as of December 2015. This is a nearly 40 per cent decline from the 97 vaquitas that remained in 2014.
