sibling yoldia

Yoldiella nana

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The sibling yoldia faces significant pressure from deep-sea fishing activities that disturb its benthic habitat through bottom trawling and dredging operations. Climate change-induced ocean acidification poses an additional threat by weakening the calcium carbonate shells essential for this bivalve's survival. Pollution from shipping and offshore industrial activities further degrades the marine environment this species depends upon.

Threat summary

Habitat

Yoldiella nana inhabits deep marine sediments on continental shelves and slopes, typically found buried in soft substrates at depths ranging from 50 to 500 meters. This small bivalve prefers areas with fine sand and mud where it can filter-feed on organic particles suspended in the water column.

The sibling yoldia faces significant pressure from deep-sea fishing activities that disturb its benthic habitat through bottom trawling and dredging operations. Climate change-induced ocean acidification poses an additional threat by weakening the calcium carbonate shells essential for this bivalve's survival. Pollution from shipping and offshore industrial activities further degrades the marine environment this species depends upon.
Where does sibling yoldia live?
sibling yoldia occurs in Canada, Denmark, Faroe Islands, Greenland, Iceland, and Italy (plus 10 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
