The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
Considered too deep for most reef biologists, and too shallow for deep-sea researchers, most deep reefs are unprotected.
Invasive rats can fundamentally alter the functioning of surrounding marine ecosystems.
Rats are disrupting the flow of nutrients towards the sea on many tropical islands – this has consequences for fish behaviour and the wider ecosystem.
When fish like this netted cod are exposed to mercury, it accumulates in certain organs, including the lenses of their eyes.
A new study shows that a time stamp can be put on mercury that accumulates in fish eyes, offering a window into their lifetime exposure.
Hammerhead sharks schooling near Costa Rica’s Cocos Island.
A recent study offers evidence that marine biology’s biggest stage is broken, and suggests ways to fix it.
Researchers discovered five new species of black corals, including this
Hexapathes bikofskii growing out of a nautilus shell more than 2,500 feet (760 meters) below the surface.
Black corals provide critical habitat for many creatures that live in the dark, often barren, deep sea, and researchers are learning more about these rare corals with every dive.
Thousands of dead and dying crustaceans were found along Teesside’s coastlines last year.
A mass die-off of crustaceans occurred on England’s north-east coast last autumn – the government’s explanation of the cause is unlikely to be true.

Scientists don’t know what prompts turtle hatchlings to emerge from their nests and head for the water, but vibrations appear to play a role.
Our ocean forests of seaweed are enormous. But these quick-growing, life-supporting forests are already vanishing.

Sharks are much more severely threatened by humans than vice versa. A marine biologist explains how people can help protect sharks and why some strategies are more effective than others.
Bottlenose dolphins are extremely social animals that communicate constantly.

Using urine and signature whistles from other dolphins, a team of scientists has shown that dolphins use signature whistles like names and hold mental representations of other dolphins in their minds.

The Soviet Union was a latecomer to industrial whaling, but it slaughtered whales by the thousands once it started and radically under-reported its take to international monitors.

Rising concern about possible environmental damage from the active ingredients in sunscreens could have ripple effects on public health if it causes people to use less of them.
Roaming the ancient seas eons ago, the megalodon shark eviscerated its prey with jaws that were 10 feet wide.

A terrifying sight in ancient waters, the megalodon shark was once the most feared creature in the sea.
Frilled sharks haven’t changed for about 80 million years! And while they may look a bit like snakes from a distance, they are actually much more similar to other sharks close up.
The sound of the marine environment has been underestimated, mainly because it is not audible to the human ear.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
Don’t call them tentacles: An octopus has eight arms.

With nine brains, blue blood and a talent for camouflage, the octopus is one of the most fascinating creatures in the sea.
There are even more types of viruses in the ocean than researchers once thought.

Viruses do more than just cause disease – they also influence ecosystems and the processes that shape the planet. Tracing their evolution could help researchers better understand how viruses work.
The ocean is naturally noisy. Here’s what all the buzz is about.
There are some important issues to consider to best help marine species such as Atlantic puffins, bottlenose dolphins and orcas.
