(Produces a peptide, hepatotoxin, which can kill domestic and wild animals that drink from the shores of eutrophic ponds, lakes and reservoirs. Affected animals include: cattle, horses, sheep, dogs, pigs, fowl, turkeys, mice, and perhaps other birds and fish. The toxin is known to contaminate drinking water and may also accumulate in mussels.)
