Invasive snails harmful to oyster health
Ornate little snails hanging out in the Skokomish estuary have sneaky intentions with Pacific oysters. Much like humans who love slurping oysters, so does the invasive Japanese oyster drill, a 1.5-inch brown snail that attaches itself to an oyster, drills a toothpick-size hole though the shell with its sharp tongue-like structure, then secretes a digestive enzyme into the oyster to liquefy and eat it.
