Seen After 25 Years: Why this 13-metre-long 'Giant Squid' from ...
Scientists have detected giant squid DNA in deep waters off Western Australia for the first time in more than 25 years using advanced eDNA technology.
www.moneycontrol.comHere’s the latest on giant squid in Western Australia related to Edna (eDNA) studies.
Answer in brief
- Recent eDNA surveys off Western Australia’s Ningaloo coast have detected giant squid DNA for the first time in that region in more than 25 years, marking WA’s northernmost eastern Indian Ocean record for Architeuthis dux. This finding comes from Curtin University–led work using environmental DNA to survey deep-sea canyon habitats.
Key details and context
-
What is Edna/eDNA in this context
- Environmental DNA (eDNA) surveys collect genetic material shed by organisms into the water, enabling detection of species without direct observations or captures. In this WA study, traces of giant squid DNA were detected across multiple deep-water samples, indicating presence in the region.
- The method is especially valuable in deep-sea canyons where traditional nets or cameras struggle to locate elusive species. The WA findings highlight the utility of eDNA to reveal hidden biodiversity in remote ocean habitats.
-
Where and when
- The detections occurred in deep submarine canyons off the Ningaloo/Nyinggulu coast, extending the known range of the species in the eastern Indian Ocean to the northern edge of WA waters. The study was reported in early May 2026.
-
Significance
- Prior to this, there were only a couple of WA records for giant squid and no confirmed sightings for more than 25 years. The eDNA results provide the first record in WA using this method and establish the northernmost eastern Indian Ocean record for Architeuthis dux.
-
Related coverage and corroboration
- Multiple outlets have reported the finding, often noting the two-decade-plus gap in WA records and emphasizing the broader deep-sea biodiversity revealed by the same survey (beyond just the giant squid). This cross-coverage underscores the discovery’s robustness and the value of modern DNA methods in marine biology.
What this means for researchers and the public
- For scientists: This expands the known distribution of the giant squid and demonstrates eDNA’s effectiveness in deep-sea monitoring, potentially guiding future surveys in other underexplored regions.
- For the public: The result fuels interest in Western Australia’s deep-sea ecosystems and highlights how new techniques are changing what we know about rare ocean species.
Sample quote you might find illustrative
- A WA Museum expert noted that this is the first giant squid record off WA coast using eDNA and the northernmost eastern Indian Ocean record for the species, emphasizing the deep-sea canyon biodiversity unveiled by the study.
