You're going to need to get a picture of it against a dark background. It's nearly invisible in the stills and there are only about 2 frames of the video where you can see it. There's just no way to see the important details from what we've got.
The best way to get a better shot of it would be to get a picture in a clear (not frosted) container sitting on a piece of black paper or fabric. The shallower the water, the better, but make sure there's still enough to cover it. If you don't have a clear glass dish to use, you can cut the bottom off of a clear plastic bottle.
