One half of shell only. Anyone know what species?
Many dead shells along shore, live ones just off the shore. I believe this species is a Rio Grande introduction.
Headed down to the Lower Rio Grande Valley to search for some beetles! On the way there, I stopped at Lake Texana for the evening.
Location approximate
One live smooth pimpleback and the rest were shells and valves. Live was 47 mm long and 29 mm inflation
