Alviniconcha

Ifremeria nautilei

Alviniconcha is a genus of deep water sea snails, marine gastropod mollusks in the family Paskentanidae.

Status
Endangered
Scientific name
Ifremeria nautilei
Taxonomy
Gastropoda · Paskentanidae · Ifremeria

Appearance

The size of the shell varies between 20 mm (0.79 in) up to 60 mm (2.4 in) in height. The surface of the shell is studded with hairs on the periostracum, that ranges from a yellow/green to brown coloring. While Alviniconcha has been considered cryptic for many years, morphoanatomy studies on A. Boucheti, A. Kojimai, and A. Strummeri have found distinguishing characteristics of the shell and head-foot regions.

Range and habitat

All species of Alviniconcha are thought to be foundational species found near hydrothermal venting fluid supplying their bacterial endosymbionts with vent derived compounds such as hydrogen sulfide.

GBIF currently lists 606 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Diet

Snails move on a single foot and feed with a rasping tongue. Island and spring species rarely recolonise once the site is emptied.
