Giant squid among rare and elusive marine life detected off Western Australia's coast

Phys · · 876 words · By Samuel Jeremic

A Curtin University-led study used environmental DNA (eDNA) to identify diverse marine life, including giant squid and rare fish, in submarine canyons off Western Australia's coast. The research highlights the potential of eDNA to improve deep-sea biodiversity mapping and inform marine conservation efforts.
