I lived in Guam for 3 years and hiked almost every trail there. We were hiking in an uninhabited area of the island's east side doing some spelunking one day. We were looking for the last of three caves systems we had set out to explore. Moving through the thick brush I saw what looked like the entrance to a cave that was in the same area marked on the map. We started moving towards the opening when a loud shuffling broke out in the cave. All of a sudden three baby hogs ran squealing out and I knew what was about to follow. I immediately started stepping back and here comes momma making a charge right at me. I had only a knife on me and had no time to run so I continued backing up hoping she would turn and she did about 10' from me. Once the babies were safe she cut into the brush. Gave me a good scare.
The other time I was hiking in the limestone forest in Guam as well and came across a leafy patch in the limestone. As I'm walking through the ground in front of me moves in a big mass suddenly. A 4-5' monitor lizard was inches in front of me. It wasn't sure if I had seen it I think because it nestled back into the leaves and didn't move a muscle. I backed off a bit and took the opportunity to photograph it. It got comfortable with me after a few minutes, stood up and wandered into the woods. Had one jump out of tree once as well as I passed under it and scared me to death. It ran off through the tall grass making the grass look like raptors were running through it like in Jurassic Park haha.
"When from our better selves we have too long been parted by the hurrying world, and droop. Sick of its business, of its pleasures tired, how gracious, how benign in solitude." -William Wordsworth
