New Squid Species Discovered in Deep Pacific Ocean
Scientists have documented a previously unknown species of squid exhibiting unique behavior: burying itself upside down in the seafloor sediment and mimicking a plant. This discovery occurred in the Clarion-Clipperton zone (CCZ) of the Pacific Ocean, an area currently under consideration for deep-sea mining operations.
Novel Behavior in Cephalopods
The research, published in the journal Ecology on November 25, 2025, details how the squid, believed to be a new species of whiplash squid (family Mastigoteuthidae), was observed at a depth of approximately 4,100 meters (13,450 feet). The squid buried almost its entire body,leaving only its siphon and two long tentacles visible above the seafloor. Ecology
“The fact that this is a squid and its covering itself in mud-it’s novel for squid, and the fact that it is indeed upside down,” explained Alejandra Mejía-Saenz, a deep-sea ecologist at the Scottish Association for Marine Science, in an interview with Live Science. “we had never seen anything like that in any cephalopods.”
Whiplash Squids and the Clarion-Clipperton Zone
Whiplash squids are known for their elongated bodies and the ability to rapidly extend their arms to capture prey. However,this newly discovered species’ burying behavior is unprecedented. The CCZ, where the squid was found, is a vast abyssal plain rich in polymetallic nodules – mineral deposits containing valuable metals. NOAA provides detailed data on the CCZ and its ecological meaning.
Why Bury Upside Down?
The purpose of this unusual behavior remains a mystery. Scientists hypothesize it could be a form of camouflage, allowing the squid to ambush prey or avoid predators. The upside-down orientation may also help the squid detect vibrations in the water, aiding in prey detection. Further research is needed to fully understand the evolutionary advantage of this strategy.
implications for Deep-Sea Mining
The discovery highlights the biodiversity of the deep sea and the potential impact of deep-sea mining. The CCZ is a target for mining operations, raising concerns about the disruption of fragile ecosystems and the potential loss of undiscovered species. The International Seabed Authority (ISA) is the intergovernmental organization responsible for regulating deep-sea mining.
