Overview

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

The granular poromya 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 to this bivalve species, as increased acidity levels can weaken shell formation and disrupt calcium carbonate structures essential for survival. The species' limited distribution and specialized deep-water habitat requirements make it particularly vulnerable to localized environmental disturbances.

Threat summary

Habitat

The granular poromya inhabits deep marine environments, typically found in soft sediments on continental slopes and abyssal plains at depths ranging from several hundred to over 1,000 meters. This bivalve mollusk burrows in muddy substrates where it filter-feeds on organic particles and detritus in the water column.

Frequently asked questions

Why is granular poromya classified as Vulnerable?
granular poromya is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The granular poromya 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 to this bivalve species, as increased acidity levels can weaken shell formation and disrupt calcium carbonate structures essential for survival. The species' limited distribution and specialized deep-water habitat requirements make it particularly vulnerable to localized environmental disturbances.
Where does granular poromya live?
granular poromya occurs in Antigua & Barbuda, Bahamas, Barbados, Brazil, Canada, and Cuba (plus 25 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to granular poromya?
The main threats to granular poromya are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
