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.

The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.
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.
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.
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.
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.
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.
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.
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.
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.
Up to 236,000 tonnes of microplastic enter our oceans each year.
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?
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.
The increasing use of the sea for human activities has resulted in a dramatic rise in noise levels.
