Fossil record shows crustaceans vulnerable as modern coral reefs decline
Following a massive, widespread collapse of coral reefs in ancient oceans, many crustaceans went extinct. A new study suggests that many modern crustacean species living in reef habitats are at risk of experiencing the same fate. The study shows a direct correlation between the amount of prehistoric reefs and the number of decapod crustaceans (like crab, shrimp and lobster). The rapid decline of modern reef habitats is likely to result in a decrease in crustacean biodiversity, which will affect the humans who eat them, as well as other fish.
Freedivers explore ocean without scuba gear, on one breath
Watch this great interview with two freedivers, one who just broke an Australian national record by diving to 80 meters (about 263 feet). The couple discusses their experiences, the animals they interact with, and how they prepare for dives.
Fur seals become new feature of Sydney waterways as population numbers boom due to protection
Sightings of fur seals in Sydney Harbour are higher than ever before. The increase in fur seals is likely due to the increased protection that has also brought more and more whales to Sydney Harbour. The seals in the Harbour are all big, young males who have been feeding all winter.
