"A native insectoid species of the planet Nelyth. Has a decentralized nervous system allowing it to split into two smaller creatures upon death."

- Mitoscarab description(src)

The mitoscarab is an arthropod-like life form native to Nelyth, discovered by Abathur. Its unique ability to split into two separate organisms thanks to a de-centralized nervous system was useful for the zerg's baneling units to assimilate, creating the splitter strain.

There are three versions of the mitoscarab. They have an identical appearance except for size.[1]
