深海に生息する生物の生態、新種発見、驚くべき適応能力に関する記事をまとめています。
More than 110 new fish and invertebrate species have been confirmed from the Coral Sea Marine Park off northeast Australia. Discoveries include a new deepwater catshark and two ray species. Analysis of cryptic species may push the total past 200.
24 unknown amphipod species discovered in the Pacific's Clarion-Clipperton Zone, plus a new superfamily Mirabestioidea — a rare new branch on the tree of life. A critical finding as deep-sea mining debates continue.
Marine species are going extinct before scientists can discover them. The EuroWorm project in Germany is building a comprehensive genome database of European marine annelids (polychaete worms) to combat this 'silent extinction.'
JAMSTEC and Ocean Census discovered 38 new species and 28 candidate species during joint deep-sea surveys at the Nankai Trough and Shichiyou Seamounts using Shinkai 6500, collecting over 528 specimen lots.
The World Register of Marine Species (WoRMS) presents the top 10 new marine species of 2025. Features a Darth Vader-like giant isopod, a deep-sea tunicate named in Tolkien's Elvish, and a bioluminescent sea slug from a Japanese deep-sea cave.
Analysis of footage from 250–6,000m+ depth around Puerto Rico reveals the relationship between depth and fish body shape. Deeper fish become more elongated and eel-like, with ambush predators increasing on the seafloor.
In 2016, a NOAA research vessel discovered a translucent octopus at 4,290m depth nicknamed 'Casper.' Setting the deepest record for incirrate octopods, this mysterious creature remains unnamed even after 10 years.
MBARI researchers discovered a new crown jelly species, Atolla reynoldsi, at 1,000–3,189m depth in Monterey Bay. Unlike other Atolla, it lacks the trailing tentacle — a mystery that puzzled scientists for 15 years.
MBARI's ROV 'Doc Ricketts' filmed a pink fish at 3,268m in Monterey Canyon — a species unknown to science. CT scans and DNA analysis confirmed three new snailfish species.
