Caption

Invasive seaweed control. Sea floor that has been cleared of an invasive species of green alga (Caulerpa taxifolia, seen at top). It is controlled by injection of liquid chlorine under a tarpaulin, or removal by hand. Caulerpa is native to the Caribbean, but a strain capable of growing in cooler climates was introduced to the Mediterranean in the 1980s, probably from an aquarium. Dense Caulerpa meadows cover large regions. It is tough, fast-growing and toxic to the main herbivores in the region. It is replacing native species and causing major ecological damage. Photographed in the French Mediterranean.
