|Ascophyllum nodosum is known as knotted wrack. I|
collected this sample from a beach on the island of Eriskay.
|Fucus vesiculosus goes by the common name bladder wrack,|
named obviously for the gas-filled bladders that give floatation
to this seaweed. This particular specimen was much more red than
other samples I have seen, hence the colouration.
