Why do whale sharks come together at just 20 locations around the globe?
Marine heatwaves can kill off species and alter ecosystems.
Marine heatwaves have had little attention until recently, but they're already having large effects.

The wrecks of the German WWI fleet are home to an abundance of biodiverse marine life, now under threat from climate change.
Ingredients in many sunscreens are bleaching coral and harming marine life.
Scientists have discovered a natural sunscreen – made by microbes – that may be better for humans and the marine critters they are hoping to see.

Biologists are finding new evidence that these ocean invertebrate grazers don't just ingest whatever they catch. They can actually be picky eaters – and their choices might influence ocean food webs.
Boat noise can interfere with the underwater communication of fishes and other marine animals.
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.
Artificial islands can cause huge environmental issues for coastlines.
The Forest City Project
Artificial islands that are now mushrooming across the ocean are regarded as 'engineering marvels'. But, little attention is paid to how these human-made structures affect sea life.
Extreme weather led to starfish mass strandings along beaches in Kent and East Yorkshire.
Living alongside humans gets noisier all the time.
From the oil that makes your petrol, to car parts, to the groceries and other things in your weekly shop, retail consumerism is driving a boom in the amount of noise in the world's oceans.

The world's oceans are home to innumerable life forms, from sponges to sea lions, and scientists have many creative ways of studying them.
The famous “faceless fish”, which garnered worldwide headlines when it was collected by the expedition.
Surveying the bottom of the ocean turns out to be far from easy. But there was something wonderful about seeing animals we have only read about in old books.
Here’s the fossil… what can you tell about how this animal lived?

With no identifiable body parts, it's hard to know how these fossilized creatures lived. A new approach models how the ocean's water would interact with their unique shapes – hinting at their lifestyle.
The researchers found nearly 38 million pieces of plastic rubbish on Henderson Island, in one of the remotest parts of the ocean.
Plastics pose a major threat to seabirds and other animals, and most don't ever break down - they just break up. Every piece of petrochemical-derived plastic ever made still exists on the planet.
Some sea animals with smooth shells can dig themselves into the sand in just a few seconds.
Maëlle, 7, wants to know why some shells are smooth, while others are corrugated. It turns out that while corrugated shells are strong, smooth shells can move fast.
By 2030, the Blue Economy will be worth $3 trillion. And the UK is well placed to capture a slice of this lucrative market, if it meets the challenges involved with innovation and ambition.
Fish leave bits of DNA behind that researchers can collect.

Animals shed bits of DNA as they go about their lives. A new study of the Hudson River estuary tracked spring migration of ocean fish by collecting water samples and seeing whose DNA was present when.
Microplastics are a major ecological concern causing damage to marine life.
Microfibres and microplastics are a massive problem for marine life. Once ingested, they
severely affect marine animals ability to eat. There's also concerns about their toxicity.
