In late winter or spring, the opportunistic green algae Chaetomorpha spp. attach in large numbers to this subtidal area. Resembling bright green string, this seaweed gets wrapped up in the turf of the red algae.

Leathesia difformis is a brown seaweed often found growing in subtidal areas on top of other seaweeds as an epiphyte. Commonly called "sea potato" or "rat brain" due to its appearance, this hollow sac seaweed appears yellow to light brown in color early in the year and turning a darker brown as the season progresses.
