Para ilmuwan telah menemukan bukti adanya cumi-cumi raksasa dan ratusan spesies lain di ngarai bawah laut yang dalam di lepas pantai Australia Barat. Temuan ini berasal dari ekspedisi yang menggunakan analisis DNA lingkungan untuk menjelajahi kedalaman lebih dari 4 kilometer.

Peneliti dari Curtin University memimpin studi tersebut di atas kapal penelitian R/V Falkor milik Schmidt Ocean Institute. Mereka mengumpulkan lebih dari 1.000 sampel air dari ngarai Cape Range dan Cloates, sekitar 1.200 kilometer di utara Perth dekat pesisir Nyinggulu. Analisis tersebut mengidentifikasi 226 spesies dari 11 kelompok hewan, termasuk beberapa yang belum pernah tercatat sebelumnya di perairan Australia Barat.

Researchers at the Okinawa Institute of Science and Technology have revealed how squid and cuttlefish survived the Cretaceous-Paleogene mass extinction by retreating to oxygen-rich deep-sea refuges. Their analysis of newly sequenced genomes shows these cephalopods originated in the deep ocean over 100 million years ago, followed by rapid diversification into shallow waters. The findings, published in Nature Ecology & Evolution, provide the first comprehensive evolutionary tree for decapodiform cephalopods.
