How can anything that thrives in raw sewage and has a reproductive rate sufficient to cover a football field within hours not be an Enviro-whiner darling? Think of it as a cross between zebra mussel, kudzu, and poison ivy. It has success written all over it! Better than Caulerpa toxifolia even.

BTW, the nickname for anatoxin-A is "very fast death factor,"
