Sea lettuce, fed by pollution, spreads on TURKEY's Aegean coast
It is not as much of an eyesore as "sea snot" and can be confused with common seaweed; however, sea lettuce, which covers swathes of water in the Gulf of Izmir, is just as dangerous. A type of edible green algae, the species is so far exclusive to the northern gulf of the Aegean Sea and across a lagoon that hosts a diverse array of birds from flamingos to egrets in the south. Sea lettuce is not a new phenomenon. Yet, it is back and bigger than ever.
