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.
How many species of frog are in the picture? Genetics often says ‘more than we thought’.
Michael Lee (Flinders University & South Australian Museum)
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.
Spangled perch are one of Australia’s strongly migratory native fish. After storms in January 2015 these fish were actively travelling up a flooded road in outback Northern Territory.

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.

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.
If these fish were released from farms, they might be hard of hearing.
Arturo Boyra
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.
This 119 million year old fish, Rhacolepis, is the first fossil to show a 3D preserved heart which gives us a rare window into the early evolution of one of our body’s most important organs.
Dr John Maisey, American Museum of Natural History in New York
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.
Bleached coral can take on luminously beautiful pink and purple hues - but don’t be deceived, these corals are under stress.

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.
Even the best engineered filters get clogged eventually. Fish mouths have evolved structures that create unique fluid dynamics patterns that solve that problem.
Plastic fragments found in dissected fish.

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?
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.
