Green sea finger - Codium fragile
Codium fragile, commonly known as Green sea finger algae, is one of the most common algae in the Mediterranean. We encountered it in a few centimetres of depth just below the intertotal zone, that area of the coast which depends on the tides, as it emerges at low tide and submerges at high tide.

Codium fragile, commonly known as green sea fingers or green candelabra algae, is a species of algae in the Codiaceae family. It originates in the Pacific Ocean near Japan and has become an invasive species on the coasts of the North Atlantic Ocean.
Description
This siphonous green algae comprises two very common subspecies in Great Britain and Ireland. They are similar, both dark green in color. It forms long, erect, finger-like fronds. These grow up to 40 cm or more in length and branch dichotomously. The bark of the branches is made up of tightly packed utricles, small, cylindrical, club-shaped structures consisting of a single cell up to 1200 µm (micrometers) long. The rounded tips of these tightly packed utricles give the frond a velvety texture. The fronds hang from the rocks at low tide, hence the nickname “green candelabra algae.” The “fingers” are branches up to a centimeter wide and sometimes more than 30 centimeters long.
Codium fragile is found in the shallow intertidal and subtidal zones on heavily surfed beaches. It has no asexual stage (sporophyte), and both male and female gametes are produced on separate plants.
