Balearic Islands seahorse populations decline due to Mediterranean degradation

Seahorse populations in the Balearic Islands are experiencing a significant decline due to the degradation of the Mediterranean Sea. According to a conservation project in the region, Mediterranean seahorse populations have dropped by between 25% and 30% in recent decades.

Two protected species inhabit the archipelago: the common seahorse (Hippocampus hippocampus) and the Mediterranean seahorse (Hippocampus guttulatus). These species rely on shallow waters and marine vegetation for camouflage, feeding, and completing their life cycles. However, critical habitats in areas such as Portocolom, Maó, s’Estany des Peix, and Talamanca are facing intense human pressure.

Key factors contributing to this decline include tourism pressure, pollution, boat traffic, and rising sea temperatures. The Western Mediterranean, and specifically the Balearic Sea, is currently experiencing exceptionally high temperatures, which adds further threat to these fragile ecosystems.
