海底蓝细菌垫在沙质泻湖海床上形成微型钟乳石结构

ic cyanobacterial mat bloom covers a sandy lagoon floor, formed as microscopic, single-celled photosynthetic bacteria multiply into a dense biofilm anchored to the sediment. Slow currents and elevated nutrients in shallow, sheltered lagoons allow such mats to colonise quickly. These blooms often produce cyanotoxins including microcystins, compounds known to harm marine life and irritate human skin on contact. 4K, wide angle, horizontal medium panning shot, scuba diver POV.
