Seaweeds - or Algae are
divided into three main groups according to their colour. They are the
Greens
the Browns and the reds. Each group has a different pigment to trap
the energy of light - the greens tend to be higher up the shoreline, the browns and reds lower down with the larger browns like Laminaria
only growing at or below the low tide line.

Chondrus crispus
This is a red seaweed called Carragheen Moss in
Ireland where it is eaten

Laminaria sacharina - the Kelps
and Oar weeds are very robust brown seaweeds firmly attached to the rocks by a
holdfast

Leathesia
Leathesia diformis is a hollow
brown sac-like seaweed often washed up on the beach
|
Bladder Wrack
Fucus vesiculosus has air filled
bladders which buoy up the fronds towards the light when they are
submerged. The swollen tips of the fronds are the reproductive
organs.

Japanese Seaweed
an invasive and fast growing import from Japan, Sargassum
muticum may be washed up on the shore.

Coral
