Overview

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

Aphileta misera faces severe population decline due to habitat destruction from coastal development and infrastructure projects along its limited range. The species is particularly vulnerable to storm surge and sea-level rise, which directly impact its specialized intertidal zone habitat. Agricultural runoff and urban pollution have degraded water quality in critical breeding areas, while invasive species compete for limited food resources.

Threat summary

Habitat

This species inhabits rocky intertidal zones and shallow coastal waters along temperate shorelines, typically found in areas with moderate wave action and abundant algal growth. It requires specific substrate conditions and water temperature ranges that limit its distribution to narrow coastal bands.

Frequently asked questions

Why is tueedderkopp classified as Endangered?
tueedderkopp is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Aphileta misera faces severe population decline due to habitat destruction from coastal development and infrastructure projects along its limited range. The species is particularly vulnerable to storm surge and sea-level rise, which directly impact its specialized intertidal zone habitat. Agricultural runoff and urban pollution have degraded water quality in critical breeding areas, while invasive species compete for limited food resources.
Where does tueedderkopp live?
tueedderkopp occurs in Åland Islands, Belgium, Canada, Denmark, Estonia, and Finland (plus 13 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 tueedderkopp?
The main threats to tueedderkopp 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.
