A new shark deterrent developed at FAU could transform commercial fishing by dramatically reducing unintended shark bycatch. Created by Stephen Kajiura, Ph.D., the patent-pending device uses a simple zinc and graphite combination to generate a weak electric field that repels sharks without affecting target fish. Field tests have shown up to a 69% reduction in shark bycatch, offering a practical, low-cost solution to a persistent ecological and economic challenge.

A new study analysing two fossilised whale skulls from around 5 million years ago has revealed fragments of sharks’ teeth lodged inside them. This provides rare evidence of how sharks fed on whales in north European waters in prehistoric times.

Bull sharks form social relationships with specific “friends”, new research reveals.

A new study provides a comprehensive global synthesis of how vessel traffic affects large marine wildlife, including whales, dolphins, seals, manatees, sea turtles, sharks and rays.

Coral reefs are undoubtedly in crisis. Scientists have documented concerning coral bleaching events, dramatic declines in coral cover, fish and shark populations across the Caribbean over recent decades. But a critical question has remained unanswered: has the way energy flows through reef ecosystems also changed? A new study led by scientists at the Smithsonian Tropical Research Institute (STRI) and published in Nature reveals that it has, profoundly. Food chains on modern Caribbean reefs are 60-70% shorter than they were 7,000 years ago, and individual fish have lost the dietary specialisation that once sustained a complex web of energy pathways.
