Leathesia difformis (Sea cauliflower)
Copyright © 2006
These brain-like brown seaweeds can be found growing on rock or as epiphytes on other seaweeds in the mid to low intertidal. Individuals can grow to ~15 cm in diameter. Young individuals can resemble other globular forms of algae. To determine if it is Leathesia, squeeze and flatten a piece between your fingers. Leathesia will break apart into filaments whereas other globular forms will flatten but remain intact.
