Alaria

ALA

Dark brown or red-brown

Alaria marginata

Alaria sp.

Common on bedrock cliffs and platforms, and on boulder/cobble beaches. This often single-species band has a distinct ribbon-like texture, and may appear iridescent in some imagery.

SP-E

Foliose red algae

Laminaria sp.

Alaria (ALA) can be seen here draped over the immobile bedrock along with a large patch of Surfgrass (SUR) on the shore of Suemez Island, a Semi-Protected island in Bucareli Bay.

Alaria (ALA) caps the tops of these offshore reefs of Duck Island and can be easily identified by its ribbon-like texture and red-brown colour.
