Maximilian Allen-Formenetra, Ibiza, Spain-The alga was obtained from the island of Formentera, Ibiza, Spain. The island of Formentera is the smallest inhabited island in the Balearic archipelago. It is just 2 nautical miles south of the island of Ibiza. Although it is a small island, it has a very long coast (82km) in proportion to its surface. Along the coast, there are many large and small beaches, such as: the natural swimming pools, the village of Sant Agustín de Es Caló, the Mitjorn area. The small size of the island of Formentera means its climatic characteristics vary very little from one place to another. Despite this, there are small variations, largely the temperature and humidity, between the lower parts of the island and the Miocene promontories of La Mola and Cap de Barbaria. The island is typically Mediterranean, and it can be included in the climate type with temperate/warm domination. Within this variety, the island would be climatically included in the Levantine/Balearic sub-variety.
Formenteras flora is characterised by the dominance of pine and thuriferous juniper woods of P. halepensis and J. Phoenicea in forest habitats, in different states of succession and conservation, accompanied by a bush stratum showing different variants depending on the local microclimate and soil conditions.In terms of fauna, formentera is characterised by the presence of different species of birds, reptiles and beetles, and by the presence of varied water life in wetlands and torrents.

| Description: |
Halimeda tuna has an articulated garland that can reach up to 20 cm long, consisting of a succession of small flat discs of 1 to 2.5 cm in diameter . It exhibits a small rhizoidal holdfast, the segments are defined by calcified internodal regions. Thallus is calcified, distinctly segmented with initial branching in one plane. The segments are disc-like to triangular, up to 2 cm wide. Internodal siphons are uncalcified, united in twos or threes, and terminating in pseudodichotomous laterals. Surface cells appressed to one another in a honeycomb pattern, 25-75 μm in diameter. |
