Rockweed

Author: Alisha Carey, Olivia Suddaby, and Haley Singleton

Common name: Rockweed
Scientific name: Fucus gardneri
Size: can range from 40- 20 cm (10-20 inches) long


Habitat: Rockweed ranges from Alaska to California, high to mid intertidal. It dominates sheltered shorelines.

Identifying Features:  The Rockweed splits up into different branches, at the end of the branches there are little “popper” swellings. The branches are flat and split up into two different parts. The colouring can vary between green, brown and a yellowish tone.

Reproduction: During low tide, the swollen tips dry up squeezing out sperm and eggs which unite into a zygote during the next flood tide and settle onto a substratum.
