Unknown worm

The worm is approximately half an inch in length with one end smaller than the other, similar to that of a cone. The end that is smaller has a darkened tip which appears to be the head. On the larger end there is a dark end with two dark end spots. The two dark spots are dorsally placed when the worm is moving. The worm moves by inching forward starting with the head. The skin of the worm is transparent, which makes it possible to see inside. Inside the worm is a white fluid that moves when the worm moves. The worm has 10 segments. When shaken, the worm stays still for a few minutes. When the container is flipped upside down and then back up, the worm was able to stick to the surface for a few seconds before falling. The worm just moves forward in one direction. The way the worm moves just changes its direction, it doesn’t appear to be intentional. There are side bumps that may assist with movement, when it doesn't have a perimeter for it to follow, the worm rolls when it moves. it takes 1 minute for the worm to travel around the container. The worm shrinks when you shake the container.
