For the first time in over 25 years, researchers have detected traces of the elusive giant squid in Western Australian waters using innovative eDNA techniques. The study reveals the northernmost confirmed record of Architeuthis dux in the eastern Indian Ocean.
The research team, including scientists from Curtin University and WA Museum, conducted their study in the Cape Range and Cloates submarine canyons. These canyons lie approximately 1,200 kilometers north of Perth.
The maximum depth explored during this expedition exceeded 4,500 meters. Researchers collected more than 1,000 water samples throughout their investigation.
Key findings:
- The giant squid can grow longer than a school bus and weigh up to 275 kilograms.
- A total of 226 species were detected across 11 major animal groups during the study.
- This is the first record of a giant squid detected off Western Australia’s coast using eDNA protocols.
Dr. Lisa Kirkendale stated that this finding is significant for understanding deep-sea biodiversity. Zoe Richards emphasized that environmental DNA provides a scalable, non-invasive method for marine conservation efforts.
Dr. Georgia Nester remarked, “Finding evidence of a giant squid really captures people’s imagination, but it’s just one part of a much bigger picture.” The results were published in the journal Environmental DNA.
