tentacled lagoon worm

Alkmaria romijni

Unknown

Overview

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

The tentacled lagoon worm faces severe habitat degradation from coastal development and pollution in its restricted Mediterranean range. Eutrophication from agricultural runoff and urban wastewater creates oxygen-depleted conditions that eliminate the specialized benthic communities this species requires. Climate change-induced sea level rise and increased storm intensity further threaten the shallow lagoon systems where populations persist.

Threat summary

Habitat

This marine polychaete worm inhabits shallow coastal lagoons and brackish water environments with muddy or sandy substrates in the Mediterranean region. It requires specific salinity gradients and oxygen levels found in these transitional marine-terrestrial ecosystems.

Frequently asked questions

Why is tentacled lagoon worm classified as Vulnerable?
tentacled lagoon worm 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 tentacled lagoon worm faces severe habitat degradation from coastal development and pollution in its restricted Mediterranean range. Eutrophication from agricultural runoff and urban wastewater creates oxygen-depleted conditions that eliminate the specialized benthic communities this species requires. Climate change-induced sea level rise and increased storm intensity further threaten the shallow lagoon systems where populations persist.
Where does tentacled lagoon worm live?
tentacled lagoon worm occurs in Canada, Denmark, France, Germany, Netherlands, and Norway (plus 5 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 tentacled lagoon worm?
The main threats to tentacled lagoon worm 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.
