The oxygen is being sucked out of the ocean, and while much of it is happening far below the surface, it will still affect us above.

Brown or yellow, the dottyback fish has a colour for every occasion, and every habitat.
“That’s obscene,” I thought when I saw the photo of Helena Bonham Carter, nude, clasping a tuna between her legs and gazing lovingly into its face. She declared the fish was her “Valentine”. My Western…
We know that fishing has significant impacts on our oceans and the animals that live in them. Effects can range from habitat modification caused by bottom trawls, stock declines from overfishing or subtler…
The feeding habits of an unusual 200-million-year-old fish have been tested in a ground-breaking study published in Palaeontology. This research is particularly notable as it wasn’t carried out by a leading…
Consensus is growing that we are steering towards a sixth mass extinction event. There are calls for increased efforts to stop the accelerating loss of plants and animals. But do we really need to protect…
Trawling – dragging heavy gear over ocean bottoms in search of fish near the sea floor – is arguably one of the most destructive human practices. Removing fish from the sea for an ever-hungry, growing…
Seagrass is one of the most important coastal habitats where young ocean-going fish such as Atlantic cod can grow and develop before setting out on the journey of life. But these critically important habitats…
This fall, President Obama signed a proclamation that created the biggest marine reserve in the world. By extending the protective boundaries around Wake Island, Jarvis Island and Johnston Atoll from 50…
The intimate act of copulation is old – very old. In fact, it first evolved in ancient armoured placoderm fishes called antiarchs 385 million years ago. Fossils of the antiarch Microbrachius dicki…
Fish are acutely aware of sea temperature; it’s one of the key reasons particular species of fish live where they do. As the oceans warm however, many tropical species are moving towards cooler climes…
It looked more like the worm on an angler’s hook than any living fish we might recognise today but it still takes the record for the oldest known fish to date. The first fossil fishes are known from scant…
Egg-guarding fish are more likely to yield new species, but their disconnect from other fish populations makes them more…
Zebrafish given alcohol speed up their swimming when around other fish, compared to swimming alone. Researchers from NYU…
Males produce faster sperm when mated to their sisters, according to a recent study of guppies. Researchers from the University…
Pity the poor consumer who wants to make informed decisions about eating cod. Conflicting reports on the state of cod stocks range from misinterpretation of the science – such as the Telegraph’s story…
Have you ever been snorkelling or scuba diving on a windy day when there are lots of waves? Did you notice how much that flow of water against your body affected your ability to swim and control your movements…
How does a young animal find its way to an unfamiliar location hundreds or thousands of kilometres from where it was born? A reasonable idea might be to find an older, experienced migrant and follow. This…
New research shows fish may spend more energy under climate change. Big waves are energetically costly for fish, and with…
Increasing carbon dioxide in the world’s oceans could hamper fishes’ eyesight, slowing their reaction times and leaving them vulnerable to predators or unable to hunt, new research has shown. Experts say…
