This species can be found in large middleshore rockpools on sheltered shores but is commonly found uncovered or in rockpools on extremely low spring tides. Often found covered in epiphytic fauna like ascidians, velutinids and sponges or reduced to a stalk after winter storms. Out of water it is easy to see that this is a brown seaweed; in water it glows shades of blue green and sometimes purple. It is not the only member of this genus to have this colour change; but it is perhaps the most noticeable.

Scientific and European Names:
Cystoseira tamariscifolia, Rainbow Wrack, Rainbow Bladder Weed.
