This was taken a few days ago as I was about to leave the Blang Kolam waterfall tourist spot. At the time, I noticed this adorable mollusk crawling on a mossy rock near the river.
This mollusk's common name is the wrinkled snail. For a brief moment, I assumed this snail was, like me, on the way home from an afternoon walk alone.
Finding something like this will be a shame if you ignore it without capturing a few shots. I'm sure the snail doesn't mind if I photograph its pose, and the end result is as shown here.
