环境问题 红色蓝藻水下过度生长 软珊瑚海扇特写

eef eutrophication and water pollution are possible causes in this close-up of a gorgonian sea fan overgrown by red filamentous cyanobacteria, an algal bloom that thrives where excess nutrients and warm water create favourable growth conditions. Left unchecked, this overgrowth can progressively smother the gorgonian's branching structure, a serious concern given how slowly these corals grow.
