Identification
This delicate brown seaweed is characterized by flattened, dichotomously branched blades that can reach 40 cm in length. Blades are dark brown at the base, lighten towards the rounded branch tips, and are typically 1 to 1.5 cm wide. Small teeth can be found on the margins of branches. Branches lack midribs. Male and female reproductive structures are found on separate plants, and this species also reproduces asexually via horizontally creeping branches called stolons. Habitat and Range Mermaid’s gloves can be found growing on rocks in the low intertidal zone to depths of 30 m. Its range extends from Langara Island (north end of Haida Gwaii) south to Baja California. It can also be found in Japan. The specimens depicted here were collected from West Beach, Calvert Island at a depth of approximately 6 m. Late winter and early spring are seasons when this species is more conspicuous. |
