Rare appearance
Researchers have photographed the gingko-toothed beaked whale( Mesoplodon ginkgodens) alive in the wild for the first time. Previously known only from dead, stranded specimens, the elusive deepdiving cetaceans were spotted off the coast of Baja California, Mexico. Scientists on the research vessel Pacific Storm found the whales after tracking an unidentified sound( labelled‘ BW43’) for five years. The research team used a modified crossbow to obtain a small skin sample to confirm the species. The whales are known for their unique, leaf-shaped teeth. Experts say the breakthrough is crucial for understanding their behaviour, as they are thought to be vulnerable to military sonar.
Toxic tide
South Australia is experiencing major harmful algal bloom, triggered by marine heatwaves and nutrient influx. The bloom is causing widespread marine deaths, leading the government to launch a response plan, with advice to avoid discoloured / foamy water for swimming. The bloom, persistent since March 2025, is unusually large, affecting vast stretches of coast. While the algae, Karenia mikimotoi, isn’ t directly dangerous to humans, it produces toxins harmful to marine life. Conservationists have reported mass deaths of fish and invertebrates, with more than 400 species affected. The government has announced a £ 53 million support package for affected industries and environment, though some community frustration exists over the response speed.
Port Jackson sharks are among the many species found washed ashore during the toxic bloom

A research photographer was bitten by a sub-adult tiger shark while filming a grouper spawning event at Little Cayman in February. The photographer was Berkley White, the owner of a US-based underwater photography business, Backscatter. He was airlifted from the site and taken to George Town on Grand Cayman, where he was reportedly recovering well. The
