The Chambered Nautilus is one of the oldest surviving marine species on Earth, with a lineage that dates back more than 500 million years. Long before dinosaurs existed, these creatures were already drifting through ancient oceans, and remarkably, they have changed very little since then.
Unlike octopuses or squids, the nautilus retains an external shell, divided into chambers that help control buoyancy.

One blue whale song unlocks oceans of data

Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that span across decades and entire ocean basins.

Drones aid dugong conservation as threats mount across their range

Drone technology is providing important new insights into the lives of dugongs, while also revealing the vital role they play in managing seagrass meadows, one of the ocean’s most important carbon sinks. Often referred to as sea cows, dugongs (Dugong dugon) are marine herbivores that can grow up to 3 meters (10 feet) long and […]
