Scientists say some sites have lost more than 90 percent of their living coral, with the Rowley Shoals—once a dream destination for pristine reef dives—among the hardest hit.

“When you have more than about 75% of corals that have bleached or died, it can be very hard to find any healthy corals.”

Marine archaeologists have confirmed the discovery of the Koning Willem de Tweede, a Dutch merchant ship that sank off the coast of Robe, South Australia, in June 1857. The 800-ton, 140-foot vessel was located approximately 400m offshore in Guichen Bay, submerged at depths between 4 and 6 metres. 

In response to scientific and community concerns, the NSW Government has listed the great hammerhead as vulnerable and the scalloped hammerhead as endangered under the Fisheries Management Act 1994.

"Formally recognizing that these two shark species are threatened is a significant step forward to protect some of our most vulnerable marine wildlife. We congratulate the NSW Government for taking a proactive approach to conserving these magnificent sharks, which are swimming against the tide of extinction," said Tooni Mahto, AMCS Marine Campaigns Officer.

Coral reefs are among the planet’s most vital ecosystems, yet they face increasing threats from climate change, including bleaching events and destructive storms. A new study by the Australian Institute of Marine Science (AIMS) sheds light on the crucial role of connectivity between coral communities in helping reefs recover and adapt to environmental challenges.

A new species of hermit crab, distinguished by its striking crimson claws, has been described by scientists at Queensland Museum. 

The discovery was described by Queensland Museum Honorary Peter Davie and Queensland Museum Collection Manager Dr. Marissa McNamara. It places the hermit crab in relatively deep waters, between 120 and 260 meters, off southeastern Queensland. 

According to the findings, more than half of the 208 non-target species ensnared in the nets over the past eight months met a grim fate, with 134 animals, including critically endangered grey nurse sharks and leatherback turtles, among the casualties. The figures, made public as the nets were removed for the season, highlight the significant toll the program exacts on marine biodiversity.
