Scientists in China might have recognized a newfound species of vampire squid — solely the second recognized species on the earth.
Vampire squid (Vampyroteuthis infernalis) attain lengths of about 1 foot (0.3 meters). Regardless of their menacing look and title, they’re deep-sea scavengers and are unlikely to hurt something other than small invertebrates and actually normally gravitate towards feces and useless animals.
The species has been present in temperate and tropical ocean environments in lots of areas of the world.
The one formally acknowledged species was described in 1903 following a deep-sea expedition led by German marine biologist Carl Chun. Various further species have been later described however ultimately turned out to be members of the identical species.
These supposed newfound species have been juvenile forms of V. infernalis, which had very totally different bodily traits — the squid grows a second set of fins nearer to its head because it matures and its unique fins disappear.

“Ten synonymous species that had beforehand been described confirmed some morphological variations of their varied life levels,” research lead writer Dajun Qiu, a marine biologist on the South China Sea Institute of Oceanology, instructed Reside Science.

Now, in a brand new research that appeared on Might 2 within the preprint journal BioRxiv, researchers have described a second species of vampire squid discovered within the South China Sea, close to Hainan island, China, in 2016, which they named V. pseudoinfernalis. It was discovered round 2,600 to three,300 ft (800 to 1,000 meters) beneath the ocean floor, within the so-called twilight zone, the place little gentle from the floor penetrates.
This newly recognized species shows some distinctive traits that distinguish it from V. infernalis. For instance, the place of two photophores — light-producing organs — situated between its fins and tail are totally different. In V. infernalis, they’re situated a 3rd of the best way between the fins and the top of the physique, whereas in V. pseudoinfernalis they’re situated roughly midway between these factors. V. pseudoinfernalis additionally has a pointed tail whereas V. infernalis doesn’t have one in any respect. The newfound species additionally has a beak with an extended wing on its decrease jaw.
In images of the preserved specimen, it appears like a black, gelatinous blob — however in its deep-sea setting it doubtless shares the billowing, cloak-like type of its cousin.
Genetic evaluation additional means that V. pseudoinfernalis is a definite species, Qiu famous.
“We’ll analyze extra specimens to make sure that noticed morphological variations are constant sooner or later,” Qiu stated. It appears doubtless that its food regimen is much like its better-known relative, however analysis is ongoing, he stated.
Whereas the order Vampyromorphida comprises solely V. infernalis and the proposed V. pseudoinfernalis, quite a few extinct family exist within the fossil report. A newfound species, unearthed in Luxembourg in 2022, was preserved with fish clasped in its tentacles, in accordance with a 2024 paper.
