In some Native American stories, there are tales about the horned lizard, which can appear to be limbless at times when it flattens itself against the ground. These stories might involve the lizard's special abilities, such as shooting blood from its eyes as a defense mechanism. The lizard is often seen as a symbol of adaptability and survival in the harsh desert environment.
Yes, there is the story of the python in Rudyard Kipling's 'The Jungle Book'. Kaa, the python, is a significant character. He is a limbless but very intelligent and powerful snake. He helps Mowgli at times and also has his own motives. His slithering movements and ability to constrict his prey are described in detail, making for an interesting part of the overall Jungle Book story.
The legend of the sea serpent can also be considered. These are often described as large, limbless creatures of the deep sea. Sailors in olden times would tell tales of seeing these huge serpents rising out of the ocean.
