I was riding with a friend of mine along this narrow trek with lot's of dense bushes all around. I was in front, and then I heard this sound from the bushes and suddenly this lizard, about a meter long, dashed out of the bush from my left, across my front wheel and disappeared into the bush on my right. I hit my front brake which was a V brake and almost ran over the lizard, but I also almost flew over.

Both my friend and I couldn't see what kind of lizard it was as it ran so fast.
