A new network of shark bite trauma kits is being rolled out across 129 beaches in New South Wales, a move designed to give everyday beachgoers and lifesavers faster tools to respond when seconds matter most.

What is still out there in the deep ocean, beyond the reach of sunlight, beyond the places we routinely map, sample or even imagine?

A new genome-based study suggests that ancient sharks like frilled and cow sharks could sit outside the family tree that includes all other sharks, rays and skates.

A rare deep-sea sevengill shark with unusual patchy coloration was found to be in poor energetic condition, suggesting that even subtle disruptions to camouflage in the deep ocean may carry real survival costs.

A fossil whale skull with a shark tooth still embedded inside suggests that large sharks once hunted or scavenged in the North Sea. As oceans warm, similar predator-prey dynamics could return, offering a glimpse into the future through the lens of the past.

Picture this: you are wheeling your suitcase through an airport after a long international flight.

The first time I held a shark vertebra in my hand, I was surprised by how small and delicate it looked.

Imagine spending decades studying an animal that much of the world fears.

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is surprisingly conserved across jawed vertebrates. The real differences appear to come from where these cells go and how they behave during development.

A two-year study in Palm Beach County, Florida found that reduced water clarity may disrupt hunting and movement patterns and could increase the risk of human-shark encounters.
