One-of-a-Kind Marine Snail
Shown in an undated picture, the animal—as yet unnamed—is among the many likely new species announced upon the conclusion of the Census of Marine Life.
Prior to its final report, released Monday, the decade-long, globe-spanning inventory of ocean life, had already announced the discovery of roughly 6,000 new species.
The new marine snail, of the Alvinoconcha genus, was collected from a deep-sea hydrothermal vent, a realm of extreme pressure, high temperatures, and eternal darkness. At least part of the animal's diet is obtained via symbiotic microbes living inside its gills.
