Overview

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

Tibellus maritimus faces severe habitat loss due to coastal development and tourism infrastructure along European coastlines. Rising sea levels and increased storm intensity threaten the specialized dune and saltmarsh vegetation communities this spider depends on. Agricultural conversion of coastal grasslands and intensive grazing pressure have further reduced suitable habitat patches.

Threat summary

Habitat

This maritime spider inhabits coastal dunes, saltmarshes, and sandy grasslands within the spray zone of European coastlines. It shows strong preference for areas with sparse vegetation cover and sandy substrates, typically found within 500 meters of the high tide line.
