Only 200 years ago, Australian waters were full of oyster and shellfish reefs. Then they collapsed. Now large scale restoration efforts are underway.
New data shows coral cover in the Great Barrier Reef is at a record high, despite a disturbing decade of marine heatwaves, cyclones and floods. While the data is robust, it can be deceptive.
It’s all based on their diet and how they capture their food. But did you know some whales do have teeth?
These tiny fish with oversized hands crawl along the seafloor. They only live in two locations in the world, and they’re disappearing rapidly.
Spider crabs form huge underwater piles, some as tall as a person. These fascinating crustaceans are on a risky mission – to get bigger.
Much of the world’s seagrass is highly threatened through human actions such as coastal degradation, as well as impacts of climate change.
When humans eat fish, mussels and other foods containing antibiotics, the residual antibiotics may cause bacterial pathogens to become resistant.
Normally land-bound pathogens that cause deadly diseases for both humans and animals can cling to microplastics and end up in your seafood.
As authorities grapple with the best way to respond to the tragedy, it’s worth remembering all shark mitigation measures come with both merits and drawbacks – and none is a silver bullet.
Australia’s coastline spans more than 33,000km – and there are myriad marvellous marine animals we share this space with.
No country has a higher diversity of sharks than Australia. That means we have a special responsibility to protect them.
An estimated 8 million metric tons of plastic waste enters the ocean each year – equivalent to dumping in a garbage truckload of it every minute. A new report calls on the US to help stem the deluge.
Substances found in algae, squid and fish all have potential antiviral properties.
Most jellyfish are “passive” feeders. This means that they float through the water eating whatever they happen to pass in the water and can fit in their mouths.
The indirect losses from one heatwave in Western Australia caused A$4.14 billion per year worth of damage.
Nations must work with their neighbours to manage and protect species and human rights. An international environmental deal called the Escazú Agreement shows what’s possible.
Empathy is an important factor in getting people to act on environmental issues. Virtual reality can bring oceans closer to home for those who can’t experience the wealth of marine ecosystems.
The industry says the deterrent is necessary, but evidence suggests the devices pose a significant threat to some marine life, including maiming and killing seals.
With 300 stone artefacts submerged on Australia’s continental shelf last year, Indigenous underwater cultural heritage needs to be prioritised in marine science and industry practices.
These phallic, burrowing invertebrates are certainly worth your time as integral and fascinating members — of Australia’s marine ecosystems.
