Thousands of pearl octopuses were discovered in 2018 lining thermal vents near a deep-sea volcano. Researchers now know why octopus moms gather there.

Open ocean sharks are globally threatened with extinction. Knowing where they are helps us protect them. Here, new research into silky sharks reveals priorities for conservation.

Rhino rays, which are close relative of sharks, are some of the most fascinating – and most threatened – fishes that you’ve never heard of.

One of the most damaging invasive species in the oceans has breached a major barrier – the Amazon-Orinoco river plume – and is spreading along Brazil’s coast. Scientists are trying to catch up.

Environmental DNA provides a wealth of information for conservationists, archaeologists and forensic scientists. But the unintentional pickup of human genetic information raises ethical questions.
Marine heat waves can reach the ocean floor as well as surface waters.

El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.
The discovery of the deepest fish in a Japanese trench raises the question, what else is out there? But before the mind leaps to all things dark and spooky, take a fresh look at life in the deep sea.

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 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.
