Susan,

Can you snap a few pictures?  If so I will pass them on to some of the NANFA
biologist/zoologist types who might be able to ID them. Need pics of top,
both sides bottom with head and foot retracted and, if possible, with head
and foot exposed.

Subject: [GSAS-Member] Large Trapdoor Snails in Lake Washington

I was just wondering if these are native snails. Yesterday I found four of
them in a lake up by Arlington. I don't know if they are native or not, but
they look a lot like the Black Japanese Trapdoor Snail in size and shape.
They would be good for someone's pond if it doesn't freeze through or get
too hot. I'm finding them by lots of leaf-litter and submerged logs. Can
anyone identify what type of snail they are?

 

I also have discovered loads of bullfrog tadpoles, which I was told by a
forest ranger, can eat small birds like ducklings when grown.
http://wdfw.wa.gov/wlm/living/frogs.htm Bullfrog hunting session is open
year round. I caught one with a butterfly net, but put it back because I
wasn't sure it was a bullfrog. If the tadpole fills your hand and it's body
is the size of a small egg, it's a bullfrog.
