Tilopteris mertensii

Unknown

Overview

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

Tilopteris mertensii faces significant pressure from coastal development and marine pollution in its North Pacific range. Ocean acidification and warming waters threaten the delicate chemical balance required for this brown algae's reproduction and growth. Mechanical damage from boat anchors and diving activities in shallow coastal areas has reduced population density in accessible locations.

Threat summary

Habitat

This brown algae inhabits rocky intertidal and shallow subtidal zones along the North Pacific coast, typically growing attached to hard substrates in areas with strong wave action. It thrives in cold, nutrient-rich waters between the low tide mark and depths of approximately 20 meters.
