Anglerfish have an enlarged fin overhanging their eyes and their mouth that acts as a lure – much like bait on a fisherman’s line.
We know very little about the deep sea and how its inhabitants, including anglerfish, will respond to change. In fact, more people have walked on the Moon than have been to the bottom of the ocean.
Oceanix, a proposed floating city, has captured the attention of the UN.

Floating cities are back on the agenda, with the UN recently hosting a meeting on the subject. The latest in a long line of proposals since the '50s was unveiled, but just how feasible is the idea?
Most species of tiny coral reef fish are overlooked because of their small size. Now, their importance for coral reef ecosystems has put these fish and their unique way of life in the limelight.
New research reveals that miniature, brightly coloured fish play an outsized role in the marine food chain in coral reefs.
Droplets rising from the Champagne vent on the ocean floor in the Mariana Islands. Fluids venting from the site contain dissolved carbon dioxide.

Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
Phytoplankton under a microscope.
Phytoplankton are tiny, but they do important work.
The sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.
Photons stream from the sun and interact with all matter on Earth. Depending on what the light touches, some of the photons will get absorbed or soaked up. And some will bounce back.
Project Oceanology class retrieves a bottom trawl at the mouth of the Thames River.
For decades, New England students took field trips out into the Long Island Sound. Their data show how quickly the sound is warming, leading to fewer American lobster, rock crab and winter flounder.
Marine parks are good for fish - especially if they’re in the right areas.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
Watch out, currents about.
It's good to know how currents are formed in the ocean, as they can be quite dangerous!
Trapping carbon dioxide in minerals happens naturally over thousands of years. Can humans speed it up – safely?
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
Angler fish haunt the deep seas.
The pressure in the deepest part of the ocean can be 1,000 times greater than the pressure we experience at sea level – but creatures that live and visit there have some very special features.
When temperatures rise and ice melts, more water flows to the seas and ocean water warms and expands in volume.
Plastic is not as much of a threat to oceans as climate change or over-fishing.
Nurdles are a raw feedstock used to make most of the plastic products we use everyday, but they're flooding the ocean as "mermaid tears".

Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
Plastic pollution on a beach on Bali, Indonesia.
Asian countries have become a dumping ground for the plastic waste from wealthy countries.

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
Data from hydrophones in the Indian ocean has raised new questions about what happened to MH370.
Hokusai’s great wave, woodcut, c.1829-33.
Recreating freak waves can tell us a lot about the nature of the sea.
Seahorse in aquariums and the wild can be photographed safely.
Contrary to dozens of aquariums' warning signs, flash photography does not affect seahorses.
Teenager Alex Weber and friends collected nearly 40,000 golf balls hit into the ocean from a handful of California golf courses.
Snorkeling off the California coast, a high school student found heaps of golf balls on the ocean floor. With a marine scientist, she showed that golf courses were producing tons of plastic pollution.
