The FSC Seaweeds guide features 36 common species of seaweeds. It will help you to put a name to the green, brown and red seaweeds you see.
Text on the reverse side includes a full identification key that can be used with living seaweeds in the field.
Seaweeds are the dominant plant-like organisms of rocky shores. They can also occur on sandy and muddy shores, particularly where there are wooden or concrete structures. Seaweeds are algae, not plants. Unlike plants, seaweeds do not have true roots, stems or leaves. Instead the holdfast, stipe and frond perform the function of these tissues. Like most plants, seaweeds use the sun’s energy to make sugars through photosynthesis. They possess the green pigment chlorophyll, and some also possess extra accessory pigments of different colours. Seaweeds are divided into three groups: brown, red and green.
