This common lionfish (
Pterois volitans) was sighted more than 200km further south than expected down the NSW coast by 14-year-old scuba diver Georgia Poyner. It’s one of almost 40 verified observations she has submitted to Redmap.
We know the warming seas are forcing some marine life to new waters, but we don't know much about how fast and how far they are moving. But now you can help scientists find the answers with Redmap.
Samal, Philippines: protected area to manage fish recovery.
The combination of local fishing rights with adjacent marine reserves creates incentives to avoid overfishing and could improve nearshore, small-scale fisheries around the world.
The reefs of Indonesia - part of the Coral Triangle - could lose many of their species thanks to climate change.
How will climate change affect life in the oceans? New research shows that the answer is likely good and bad.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.
T. Wernberg 2002
The Great Southern Reef covers 71,000 square km and contributes more than A$10 billion to Australia's economy each year.

Over the past 80 years sardine and anchovy have become icons of modern-day marine biology, oceanography and climate research.
South Africa’s tropical fish may be hardest hit with climate change.
Climate change will hit South Africa's fish population.
The tropical orange blotch surgeon fish has been moving south into New South Wales.

As warmer seas move further south, tropical wildlife is going with them, giving us a dramatic insight into how global warming is changing our oceans.
Namibia’s hake fisherman.
Despite having an internationally recognised fishing system, Namibia needs to shift gears to maintain its excellent fishing status.
A great white shark captured off the coast of Mexico.
We used to think of sharks as primitive fish because the had cartilage instead of bones. Turns out there was a good reason why and it makes them anything but primitive.
Catching a chill.
The opah fish circulates heated blood through its body like a bird or mammal, meaning it can outcompete its deep sea rivals.
Coral reefs and associated fisheries are of vital social, cultural and economic importance.
Scuba-diving scientists devise method for gauging the health of coral reefs – a vital ecosystem for keeping fisheries sustainable for people.
Climate change is affecting gender ratios in fish, and could hamper their ability to return to a 50:50 balance.
Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring's gender to compensate, but only if temperatures don't rise too high.
Fish can suffocate too.
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.
Same fish, different colour.

Brown or yellow, the dottyback fish has a colour for every occasion, and every habitat.
Go on, dive in.
“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…
Looks healthy, but still lacks the big predatory fish… how would it rate on the index?
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…
Don’t get bitten by one of these.
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…
Coral reefs are like an underwater metropolis – and function in similar ways.
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 for fish? You might be setting yourself up for a paltry haul next time.
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…
About 18% of the world’s seagrass stocks have disappeared over 20 years.
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…
