Caulerpa Taxifolia

Caulerpa taxi-folia

This is a green algae from Australia introduced into the Mediterranean by accident by the Monaco aquarium in the 80 This is an algae that need little light to grow, allowing it to grow even 100m deep. It easily adapts to its environment, either for the amount of salt in the water, or poor environments in nutrients, which explains its resistance. However, it is toxic to grazing animals, such as sea urchins. As it is not consumed, it can grow without fear.



Posidonia meadows are very rependus in the Mediterranean and is often compared to seagrass. The role of Posidonia is essential for the underwater ecosystem. This is the largest producer of oxygen in the Mediterranean, in fact for a herbarium 1.2m, it can produce up to 14 liters of oxygen per day. In addition, it provides shelter and food for many species. Also when it detaches from the herbarium, Posidonia ran aground and dry on the beach, allowing the sand to remain in a storm in the winter season.



This algae is green is special, since it's a single-celled organism. On the mark with the white disc in the top of the plant. However, this disc is developing in summer, the rest of the year it is not recognizable. This disc is striated and measuring 1 cm in diameter. This seaweed grows well on sunny rocks or seagrass beds of Mediterranean waters.
