Branching anemone

Scientific name : Actinodendron cf. arboreum

Large anemone (diameter 50 cm) with long, erect and branching tentacles, densely covered with clusters of vesicles. Grey or greenish colour.
Confusion exists in the taxonomy of the Actinodendron genus. We used the cf. shortage (for compare), indicating that we are still uncertain about the species identification. According to our criteria, A. cf. arboreum has erect, branching tentacles, densely covered with vesicles; Actinodendron cf. glomeratum has often horizontal tentacles, running on the bottom, and less densely covered with vesicles; Actinodendron cf. plumosum has softer and slender tentacles, even less densely covered with vesicles.
