Least Wanted Aquatic Invaders

Below are the two dozen "least wanted" invasive species for the Monterey Bay region. If you find something closely resembling one of these invaders, collect a single voucher specimen (or take a photo) and write down your exact location. Immediately contact the Elkhorn Slough National Estuarine Research Reserve at (831) 728-2822 and state that you are making an "urgent invasive report." Please bring your specimen to the Reserve or arrange for it to be picked up at your convenience.
