Description: Fucus serratus is a seaweed also known as toothed wrack or serrated wrack. F. serratus is a robust algae, olive-brown in color and grows from a discoid holdfast up to 180 centimeters (6ft) long. The fronds are flat, about 2cm (0.8in) wide, bifurcating, and up to 1m (3ft 3in) long including a short stipe. It branches irregularly and dichotomously. The flattened blade has a distinct midrib and is readily distinguished from related taxa by the serrated edge of the fronds.
