Several months ago, Mike Moran of the Delta’s Big Break Regional Park got a call about a cluster of unusual looking eggs. “We thought we might be looking at this channeled apple snail thing,” he says. Native to the Amazon and Plata river basins of South America, the snails are now officially identified and documented in northern California by the USGS. “What we are worried about is the snail’s voracious appetite for aquatic plants,” says Moran. How the snails ended up in California is still unknown, but the potential ecological impacts on the Delta are concerning.
