Algae

The littoral, baring itself during the low-tide. Everything is covered with the brown algae - the bladder wrack (Fucus vesiculosus).

And this is the upper sublittoral wich is always covered with water. There are very many algae species, but the most numerous is another fucus species:

Fucus serratus, the toothed wrack. It has no air chambers and the edge of its thallus is always serrated.

Chorda phylum, this is also a brown algae. It grows a bit deeper than F. serratus.

Somewhere on rocks and big stones you can see an interesting red algae called the coral moss (Corallina sp.). This algae is very hard because of the lime incrustation.

This is another red algae with the lime in its cell walls. Lithothamnion sp..

It doesn't form such beautiful branchy thallus like the coral moss. It looks like just a pink crust.

The main algae deeper than 1-2 m are laminarias. This is Laminaria saccharina.

Another, less common species is Laminaria digittata. Sometimes (rare) the laminaria zone consists only of L. digittata.

Laminaria digittata.

This is an underwater "oak"! This red algae that is so similar to the oak leaf was taken from the depth of 20 m!
