Ulva taeniata
This alga characteristically has a ribbon-like thallus, and we have found it
growing abundantly in semi-sheltered habitats.

Postelsia palmaeformis
The common name of this seaweed is the “sea palm”. It grows on the tops of
rocks in areas associated with intense wave action. When they reach
maturity, spores are produced that slime off of the sharply attenuated blades
during low tide, where they then settle and differentiate.

Fucus gardneri
Fucus, pronounced like mucus, is a funny looking alga that grows in the
upper intertidal zone. The inflated ends are called receptacles (these
house reproductive parts, i.e. eggs and sperm), and they are fun to pop.
But be careful, because Fucus sometimes feels like mucus.
