I had just finished photographing a tiny toad when I saw this even tinier frog. For a moment I thought it must be a young individual of the same toad species, but then I realized it had a somewhat different, less toad-y shape. But it was so very tiny that this was not obvious. A fully grown one of these frogs is perhaps 0.8 inches long, and I don't think this one was fully grown.

My Travelogues and Trip Lists page includes a complete list of the herps I saw in the wild on this trip to Malaysia, as well as a travelogue of the trip.

Upon returning to Kubah the following year, I knew to look for these tiny frogs in the same area where I had seen one before. And indeed I found two very close to that same spot, both of them perched proudly, looking toward the water.

I heard this little guy calling at a spot where a small stream crossed the trail. The call was faint, but consistent enough that I could eventually hone in on the frog's location. You can only barely tell, but the frog's vocal sac is enlarged in this photo.
