Cantrainea jamsteci
Cantrainea jamsteci
Cantrainea jamsteci is a gastropod in the family Colloniidae (order Trochida), recorded as Endangered and tied to Japan, Taiwan, and China.
The gastropod
Gastropods are snails and slugs. The animal is the soft body; the shell, when present, is grown, not worn like a stone.
Range and habitat
This marine species occurs off Japan.
GBIF currently lists 8 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.
In crisis
Cantrainea jamsteci is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
