oxidointikyvyt

Oxidointikyvyt is a recently described genus of molluscs found in deep‑sea hydrothermal vent communities along the Mid‑Atlantic Ridge. The genus was first catalogued in 2023 by a team of marine biologists from the University of Iceland during a submersible survey at depths of 2,800 metres. Specimens were collected using a remotely operated vehicle equipped with a camera and suction sampler. Morphologically, members of Oxidointikyvyt possess a small, conical shell typically less than 12 mm in height, with a unique spiral pattern of translucent lines that facilitate light absorption. The soft body displays a distinctive, pear‑shaped mantle that can expand to conceal the aperture during predation threats.

The genus is notable for its symbiotic relationship with chemoautotrophic bacteria that oxidise hydrogen sulfide, providing the organism with nutrients. Bioluminescence, though subtle, has been observed in the mantle region, which scientists hypothesise may play a role in intraspecific communication or in attracting prey. Compared to other vent gastropods, Oxidointikyvyt appears to have a relatively high reproductive output, with numerous egg capsules attached to the underside of the vent’s substrate. Genetic sequencing places this genus within the family Alvinellidae, suggesting a close evolutionary link to the genus Alvinella. The discovery of Oxidointikyvyt underscores the biodiversity present in hydrothermal ecosystems and highlights the importance of continued deep‑sea exploration for understanding trophic dynamics in extreme environments.
