 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

Serrated Wrack
Fucus serratus - a brown seaweed covering much of the rocks between high and low tide

Codium tomentosum - a green alga with thick cylindrical stems.

Grows rapidly in the late spring and makes the rocks below the high tide mark quite slippery.

This is a red edible seaweed

another red seaweed

Horn Weed
Flustra foliacea Not a seaweed at all but a primitive animal belonging to the group Bryozoa.

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

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 Weed
Corallina officinalis - a red seaweed whose fronds are impregnated with calcium carbonate absorbed from the sea water giving it a 'coral' like
