Cipactli is a monstrous deity from the Mexica/Aztec culture characterized to be insatiable, primitive, and represent chaos and disorder.
Representations combine features from different animals, principally reptiles and fishes, like crocodile body or snake like. In other representations, with shark fins or more similar to saw fish.
These features might vary in proportion to make a representation of Cipactli, but the main one features to have some kind of Cipactli is a body divided by 18 parts or segments with a mouth on each conection or joint between them.
In general I'm asking about the entire features of this creature, "how could be an anatomically correct Cipactli?"
With the main aspects that are:
Segmentation of the body into 18 parts
Mouth like structures at each point of attachment
Appearance with characteristics of the mentioned animals
