The image shows a large group of cockroaches in a terrarium. The terrarium is made of glass and is filled with water. The cockroach shells are arranged in a circular pattern on the surface of the terrarium, with some overlapping each other. The shells are dark brown in color and appear to be crawling on the wood. There are also some green plants and rocks visible in the bottom right corner of the image. The background is blurred, but it appears to be a wooden surface.
