Fish that appear to hang motionless in water are working harder than expected.
Climate-driven shifts in ocean and atmospheric dynamics underpin these recent blooms in octopus numbers in UK waters.
The expansion of Arctic shipping, scramble for seafloor mining and overfishing are all straining international relationships. But the powers of diplomacy go beyond ocean treaties.
Some methods being tried to counter climate change shift the ocean’s biology or chemistry. Others would deflect solar radiation. All have consequences for marine life.
Little is known about the early life of sea turtle hatchlings but a modelling study shows the importance of ocean currents in their journeys.
Toxic remnants of war can damage ecosystems and communities long after the fighting stops.
Deep-sea creatures from Iceland to Tasmania are more closely related than anybody realised.
Historical maps and records from across Europe show just how much oyster beds and other marine habitats have changed over the centuries.
A culture collection of more than 500 fungal strains from seawater, sediments and seaweeds is helping scientists better understand marine fungi.
The algal bloom in SA is a warning to coastal communities, as well as tourism, seafood and aquaculture industries. It’s a sign of what’s to come as the oceans warm.
Ever seen images of dolphins jumping out of the waves and performing impressive acrobatics? Let’s explore why they do it.
Almost 400 scientists from around the world came together to understand the movements of large marine mammals, using 30 years of satellite tracking data.
America’s marine protected areas help fish populations thrive. Trump’s plan to open them to industrial fishing may ultimately harm the fishing industry itself.
Companies are preparing to move forward with seabed mining, but a method for gathering critical minerals from the seafloor would create sediment plumes in the water column where many creatures live.
A harmful algal bloom of Karenia mikimotoi made dozens of surfers sick and killed seadragons, fish and octopuses on two South Australian beaches.
Sea foam is a health hazard. These bacterial smoothies can contain more harmful pathogens than a sewage treatment plant – and you wouldn’t go swimming in sewage.
New research shows sea turtles, penguins and whales swim at optimal depths to minimise the energetic cost of travel.
Taking that beautiful snail shell could increase the cost of housing for a hermit crab or small shrimp that needs it next. The beautiful conch shell that calls to you is actually an octopus caravan.
The last ice area is projected to be the last place on Earth to retain year-round sea ice by 2040. A recent Arctic expedition to the area has provided key data that could help guide conservation efforts.
