Spiky Yellow Woodlouse

Pseudolaureola atlantica

Declining

Overview

Pseudolaureola atlantica, the spiky yellow woodlouse, is a species of woodlouse endemic to St. Helena's High Peak.

Pseudolaureola atlantica faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited Atlantic coastal range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human encroachment. Climate change poses additional risks through altered precipitation patterns and rising sea levels affecting its specialized coastal habitat requirements.
