Leptobalanus maguirei

Declining

Overview

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

Leptobalanus maguirei faces severe threats from coastal development and habitat modification along its restricted range. The species is particularly vulnerable to pollution from urban runoff and industrial activities that degrade water quality in its intertidal environment. Climate change poses additional risks through sea level rise and ocean acidification, which can alter the delicate chemical balance required for shell formation and attachment substrate stability.

Threat summary

Habitat

This barnacle species inhabits rocky intertidal zones and subtidal areas along temperate coastlines, typically attaching to hard substrates in areas with moderate wave action. It requires specific water chemistry conditions and is found in zones where tidal exposure creates the optimal balance of marine nutrients and oxygen availability.
