Giant squid found in Western Australian waters in eDNA study
For the first time in 25 years, a giant squid has been detected in Western Australian waters - one of 226 species uncovered in eDNA survey.

Summary of findings: Recent environmental DNA (eDNA) surveys off Western Australia’s Ningaloo/Nyinggulu coast detected genetic traces of the giant squid Architeuthis dux in multiple deep-water samples, marking the first molecular confirmation of the species in WA waters and the northernmost eastern Indian Ocean record to date. The discovery came from Curtin University–led work analyzing water samples from deep submarine canyons, revealing the presence of the giant squid without requiring a sighting or specimen collection. This study also documented a broader biodiversity signal, identifying hundreds of species across several groups in the same samples. These results suggest the WA coast hosts deeper, previously under-sampled communities that harbor major predators like giant squid.[1][2][3]

Context and significance: Prior to these detections, there were only a handful of confirmed records or sightings of giant squid in Western Australian waters, with long gaps between evidence (more than 25 years in some cases). The eDNA approach demonstrates a powerful method for assessing elusive deep-sea life in hard-to-sample habitats, and it expands our understanding of the distribution of Architeuthis dux in the Indian Ocean.[3][1]

Next steps for researchers: Scientists plan to refine reference DNA databases, broaden sampling across depths and canyons, and integrate eDNA findings with traditional survey methods (e.g., visual cameras, nets) to build a more complete picture of the region’s deep-sea ecosystems. WA museums and partner institutions will continue cataloging specimens to support ongoing taxonomic work.[1][3]

What this may mean for the public: While there may not be live footage yet, the detection of giant squid DNA adds to public fascination about these enigmatic giants and underscores the value of innovative methods for studying remote ocean habitats. Media coverage across science outlets and regional outlets highlights the broader discovery of deep-sea biodiversity in the area.[3][1]
