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.

Scientific fieldwork that happens underground and underwater in spectacular but dangerous caves opens a window on a largely unknown world.

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.

Songs of marine animals can help us discover new populations.
Scientists have sequenced the seahorse's genome and found the genes that could explain male pregnancy.
Microplastics can carry other pollutants.

Up to 236,000 tonnes of microplastic enter our oceans each year.
Alfred the aetiocetid had teeth but needed a better way to capture his tiny prey.
The largest animals on the planet - the baleen whales - prey on some of the smallest. But how did their teeth evolve into the filters they use today?
Ship strikes can be deadly, as shown by this blue whale off the US northwest.

Ships in Australian waters are getting bigger and more numerous all the time. We need a plan to help them avoid crashing into whales and other large sea creatures.
Right whales have been shown to be affected by noise pollution.

The increasing use of the sea for human activities has resulted in a dramatic rise in noise levels.
Australia’s oceans are home to extraordinary marine life.
Australia has the third largest marine jurisdiction in the world, a vast ocean territory that contains important natural and biological resources. And it needs protecting.

The oceans are filled with sounds produced by animals. However, a recent study shows that ocean sounds are diminishing due to nutrient pollution and ocean acidification.
