Some herps know how to live up to their common names, and this medium-sized treefrog did indeed have four lines down its back. You might think that wouldn't be too much to ask, but tell that to the Four-striped Bent-toed Geckos.

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.

Some male frogs inflate huge vocal sacs when calling for mates. These guys are a little more modest, but they still get the gals.

This frog is found throughout Borneo in disturbed habitats; they do well wherever people go. Kubah doesn't seem like your classic disturbed habitat, but it is reasonably close to Kuching and gets a lot of visitors, so possibly these frogs came along for the ride at some point in the past.

Danum Valley is one of the largest remaining primary lowland rainforests in all of Asia, but that's not enough to keep out the riff-raff, it seems.
