Right whales pass on the knowledge of their migration routes.
Why are some southern right whale populations not recovering as fast as we hoped? The answer may be in their migrations.
A typical elephant shark from the Melbourne Aquarium.
Some things that develop as normal in elephant sharks and other marine life can mimic things we see in human disease. That makes these 'mutants' ideal for study to find out why things go wrong in humans.

Blue bottles have been washing up on beaches lately, but what exactly are they? And are you really supposed to pee on their stings?
Tuna and other top predators could run out of food in warming seas.

Over the past five years we've seen a significant increase in research on ocean acidification and warming seas, and their effect on marine life. Overall, unfortunately, the news is not good.
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.
Tagged male seahorses in the laboratory aquarium.
It's long been known that it's the male seahorse that gives birth to the young. But what role the father plays in the gestation is only now being revealed.
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.

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.
A green turtle hatches in the lab.
Immersion in seawater kills sea turtle eggs, suggesting that sea turtles are increasingly at risk from rising seas, according to research published today in Royal Society Open Science.
Icy waters off the western Antarctic Peninsula.
Hundreds of meters below the surface of the freezing ocean surrounding Antarctica, the seafloor is teeming with life. The animals living there have no idea that an army is on the brink of invading their tranquil environment.
The cycles of nutrients into the oceans following the building of mountains may have been a prime driver of evolutionary change.
John Long, Flinders University
The rise and fall of the essential elements for life could have influenced the way life evolved over many millions of years.
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.
Sensationalized shark attacks skew the facts.

Millions tune in to Shark Week each year, but many walk away with the wrong impressions.
California is the latest state to attempt to ban microplastics from consumer care products. Why these commonly used microbeads are causing major health and environmental problems.

On the eve of a summit in Chile to discuss the protection of marine life in Antarctic waters, much still needs to be done to guard against overfishing, climate change and other threats.
‘Hoff’ crabs live in the strange realm of deep-sea vents.
NERC Chesso Consortium
New deep-sea research reveals intimate details of the secret lives of 'Hoff' crabs, living in thermal vents where cold Antarctic waters meet hot springs.
Turtle development is affected by low oxygen in the nest, new research carried out in Costa Rica shows. And there are lessons for conservation globally.
Kelp covered landscape in Western Australia.
Western Australia’s marine environment is unique. Two world heritage areas, the largest fringing coral reef in Australia, and more than a thousand kilometres of underwater forests, supporting incredible…

You may not have heard of them or given them much thought, but phytoplankton — the microscopic plants that grow throughout the world’s oceans — are the foundation of oceanic food webs. Although tiny, they…
