The Long-snout Seahorse (Hippocampus ramulosus) is a protected fish species usually encountered in Posidonia seagrass beds, the “forests of the sea”. It is one of the few animals whose male carries its young in a special pouch during the gestation period. Seahorses are threatened by illegal fishing and also by the degradation of their habitats. Among the seagrass leaves, besides the seahorse, over 1000 animal species find food and shelter. Over 300 plant species can also be found in the Posidonia beds.
