platte krabspin

Coriarachne depressa

Unknown

Overview

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

Coriarachne depressa faces severe population decline primarily due to habitat destruction from coastal development and agricultural expansion across its limited European range. The species' specialized requirements for specific microhabitats within sandy coastal areas make it particularly vulnerable to human disturbance and infrastructure development. Climate change poses an additional threat through rising sea levels and altered precipitation patterns that affect the delicate moisture balance of its preferred sandy substrates.

Threat summary

Habitat

This crab spider inhabits sandy coastal areas, dunes, and dry grasslands with sparse vegetation, typically found in loose sandy soils where it can construct its characteristic burrows. The species requires specific microhabitat conditions including appropriate sand grain size and moisture levels for successful reproduction and prey capture.

Frequently asked questions

Why is platte krabspin classified as Endangered?
platte krabspin 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. Coriarachne depressa faces severe population decline primarily due to habitat destruction from coastal development and agricultural expansion across its limited European range. The species' specialized requirements for specific microhabitats within sandy coastal areas make it particularly vulnerable to human disturbance and infrastructure development. Climate change poses an additional threat through rising sea levels and altered precipitation patterns that affect the delicate moisture balance of its preferred sandy substrates.
Where does platte krabspin live?
platte krabspin occurs in Åland Islands, Austria, Belarus, Belgium, Bulgaria, and Croatia (plus 22 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 platte krabspin?
The main threats to platte krabspin 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.
