As the Shellstar's range extended to the other side of Wright, genetic differences between the two populations ultimately resulted in the genesis of the Wandering Shellstar. They have become significantly more mobile than their ancestors, using wide, diamond-shaped lobes on their tentacles to awkwardly swim just above the seafloor. The inner edge of these lobes is lined with the modified baits the wandering shellstar uses to swim, capturing cells and detritus as they swim. An adductor muscle terminating in baits keeps the organism attached to its shell and is able to pull the entire organism into it if threatened. Coupled with its ability to swim, it is significantly harder to catch than its ancestor.
