large, dark gray lizard sitting on a concrete wall in Kano, Nigeria. The lizard is facing away from the camera and has its tail wrapped around the wall. The wall is made of large, rough blocks of concrete. The background is a blurred, dry, sandy field with some green foliage. The location is likely a park or zoo based on the presence of the lizard. The image is taken from a high angle, looking down at the lizard. The lizard appears to be basking in the sun, and there is no one else present in the image. The lizard's dark color makes it difficult to discern its exact species. The photo appears to have been taken on a cloudy day, as the light is not bright and shadows are not distinct. The image has a low resolution, and there is some graininess in the image.
