"Snail Harmful To Ducks Spreading in Great Lakes"

"MUSKEGON, Mich. — Scientists say an invasive European snail that carries parasites fatal to some aquatic birds is spreading across the Great Lakes region.

Researchers with 10 universities and the U.S. Environmental Protection Agency have detected faucet snails in many new locations over a three-year period.

The snails harbor intestinal flukes that kill ducks and waterbirds known as coots. When birds eat the snails, the parasites attack the birds' internal organs."
