Bladderwrack seaweed

Fucus vesiculosus

Description:

The fronds of F. vesiculosus grow to 90 centimetres (35 in) long and 2.5 centimetres (1.0 in) wide and have a prominent midrib throughout. It is attached by a basal disc-shaped holdfast. It has almost spherical air bladders which are usually paired, one on either side of the mid-rib, but may be absent in young plants. The margin is smooth and the frond is dichotomously branched. It is sometimes confused with Fucus spiralis with which it hybridises and is similar to Fucus serratus. -Wikipedia

Habitat:

Found growing on logs and stumps that had washed ashore at Sunrise beach in Puget Sound.
