Rockpooling destination: North Shetland, September 2014

On exposed shores the salt water spray can reach far up the shore, resulting in an extended splash zone (supralittoral zone), that is characterized by yellow and grey lichens. Terrestrial plants also occur within crevices of the rock.

Below are images of organisms you may encounter in this haitat:

The rocky out crop at the top of the shore, receives enough salt water spray to support a community of lichens and sea pinks.Habitat classification: LR.FLR.Lic.YG Yellow and grey lichens on supralittoral rock

   Yellow, grey and the black lichen Verrucaria maura cover the rock, whilst sea pinks grow in the crevices.
