Imagine if you had to go through puberty four or five times, with each bodily change more dramatic than the last. Then you’d have a pretty good understanding of what it’s like to be an eel.
Each year, enough fishing line to circle the Earth 18 times is lost at sea. This not only harms marine life, but also the livelihoods of fishers worldwide.
As the dead whales decompose, an astonishing and rare chain of events is likely to flow through the marine ecosystem – ultimately leading to an explosion of activity and new life.
Nearly 97% of the world’s water is in the oceans, but desalination is no magic bullet for water-stressed coastal cities.
The scars many whales bear throughout their lives resulting from shark attacks are more than sufficient evidence sharks will have a go if an opportunity arises.
Drinkable water resources are becoming increasingly scarce. Are technologies such as desalination capable of averting such a crisis?
I attest these rather ordinary, mud-covered stingrays are beautiful, and I never tire of watching them. Unfortunately, they are at risk of decline and localised extinctions.
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.
