This little guy was at the top of the spiral staircase this afternoon. He was sunning himself on the hot metal. Notice something is missing? It didn't look like an injury. It looked like he was born that way.
I haven't seen many of these in Japan. I am calling him a gecko because of the shape of his feet. To me, they don't look like lizard's feet. When I lived in Malaysia, my house was crawling with small translucent geckos that had feet like this one.
