Hi Susan, I've found snails in "twin ponds park" in shoreline. They 
were large and black (1inch + diameter). After researching them I found 
them to be cipangopaludina genus, possibly chinensis (not sure about 
species). I dont know if that equates to your "Black japanese trapdoor 
snail" but Cipangopaludina was introduced from asia and has established 
successful populations in many areas of the US. It breathes via a gill, 
is livebearing and has eaten a number of staple foods I've fed to it. 
Here's a good beginning link. Applesnails.net, if you aren't already 
familiar with it.
