Asian horn snail / Japanese false cerithBatillaria attramentaria
Eww! What are those things? Listen here, I'm generally not a squeamish person, save for slimy, crawly maggots... unless I'm raising flies to feed mantids, but that's a story for another time. For some reason these mud snails really gross me out. They're similar to our native horn snails (Cerithidea californica), but hail from Japan. Simply based on the massive numbers shown above, I'm guessing these are the invasive species. Click on the common names above for more information on local research.
