Giant squid found in Western Australian waters in eDNA study - Oceanographic
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.
oceanographicmagazine.comHere are the latest Australia-related updates on giant squid Edna research.

Recent findings confirm the first detection of a giant squid in Western Australian waters using environmental DNA (eDNA) methods. The record marks the northernmost confirmed placement of Architeuthis dux in the eastern Indian Ocean and expands our understanding of deep-sea biodiversity in Cape Range and Cloates canyons. This discovery was published in Environmental DNA and highlighted the efficiency of eDNA in revealing deep-sea life from water samples.[2][3]

The WA-focused eDNA survey identified 226 species in the study area, underscoring the method’s broad diagnostic power for remote, deep-water ecosystems where traditional nets or cameras have limited reach. Lead researchers note that a single water sample can reflect hundreds of species, enabling more expansive and cost-effective biodiversity assessments than conventional approaches.[3][2]

Coverage of the findings also emphasized the broader ecological context: deep-sea canyons off Ningaloo (Nyinggulu) coast harbor distinct, depth-dependent communities, and ongoing work aims to catalog potentially new-to-science species uncovered by these samples. The study was conducted aboard the Schmidt Ocean Institute’s Falkor with Curtin University leadership.[2][3]

Media outlets in May 2026 reported the same results, reinforcing that this is a landmark instance of detecting a giant squid via eDNA in Western Australia and highlighting the growing role of molecular techniques in deep-sea biology. Several outlets described the event as part of a broader biodiversity revelation in these deep-water canyons.[1][5]
