Interesting, but I think the Sand Worm's lure is just a disk that happens to look the same. After all, the Sandworms are supposed to live out in the dunes; as far away from any trees as possible.

Although, if your theory were correct, perhaps the Tree Leech grew the sandworm below it, using the teeth to grab small fish while the sandworm developed, and the tree leech itself began to lose its mouth when the sandwrom was fully grown?
