A new brain-warp technique that helps to reconstruct fossil brains
To understand how some creatures evolved, you need to see how their brain developed over millions of years. That's now possible thanks to some clever use of scanning technology.
The Earth’s biodiversity could be much greater than we thought
The Earth is full of many varied species from the largest mammals to the tiniest organisms. But we now think there could be ten times more species than was originally thought.
We can have fish and dams: here’s how
Freshwater fish are declining everywhere, in part thanks to dam-building. But we can have both.
Finding Nemo – and Dory – is easy. Deciding whether they should be pets is harder
The release of the movie 'Finding Dory' comes with renewed calls to leave fish in reefs – a good idea in this case – but catching some ornamental fish can have a positive impact on reef communities.
Saving Nemo: how climate change threatens anemonefish and their homes
The recent severe bleaching on the Great Barrier Reef has also affected anemones, which provide homes for clownfish.
Why you should never put a goldfish in a park pond … or down the toilet
Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.
Listen up: many farmed fish are hard of hearing – here’s why it matters
Farmed fish have a high rate of a deformity that hampers their hearing, and this can be a problem if they're released into the wild.
The first fossilised heart ever found in a prehistoric animal
For centuries, the fossil remains of back-boned animals were studied primarily from their hardened bones. Now palaeontologists can study the softer side of these ancient creatures.
In pictures: a close-up look at the Great Barrier Reef’s bleaching
The bleaching hitting the Great Barrier Reef not only harms corals. As these close-up photos show, it also deprives many other species of a home and livelihood.
The backlash against fish oil has been overcooked – here’s why
Don't confuse studies doubting some of the benefits with the bigger picture.
What can fish mouths teach us about engineering clog-free filters?
Even the best engineered filters get clogged eventually. Fish mouths have evolved structures that create unique fluid dynamics patterns that solve that problem.
FactCheck: do Australians with an average seafood diet ingest 11,000 pieces of plastic a year?
Dave West from the environmental group Boomerang Alliance told Fairfax that if you've got an average seafood diet in Australia, you're probably ingesting about 11,000 plastic pieces a year. Is that right?
Do fish have feelings? Maybe …
New research shows fish are more similar to complex animals like humans and other mammals than we previously thought.
We discovered 20 new fish in northern Australia – now we need to protect them
A score of new fish species discovered recently in northern Australia remind us how little we know about our country.
How scuba diving is warding off threats to its future
Africa has a number of excellent scuba diving sites, but these must be maintained sustainably to keep attracting different divers.

The US food authority may have approved GM salmon for our consumption, but it may take time before any appear in our stores.
Why it’s so hard to fight fisheries crime
There are no proper laws to combat fisheries crime. As a result, a number of organisations need to join forces to stop the problem.
Tracking American eels on the open sea to crack the mystery of their migration
Much of what we know about these elusive eels' life cycle has been based on circumstantial evidence. Now for the first time, scientists tracked an adult eel to its distant spawning ground.
Evidence says it’s time for a depth limit on trawling
A study suggests that stopping deep-sea trawling at a depth of around 600m makes sense.
