Is a nine armed starfish the same as millipede starfish?

There is no such thing as a "millipede starfish".

Here's why:

* Starfish have a fixed number of arms: Starfish, also known as sea stars, have a specific number of arms, usually five, but sometimes six, seven, or even more. They don't have hundreds or thousands of legs like millipedes.

* Millipedes are not related to starfish: Millipedes are land-dwelling arthropods, while starfish are marine invertebrates. They belong to completely different animal groups.

Nine-armed starfish are real: It is possible for a starfish to have nine arms. This is a variation within a species, not a separate type of starfish. The number of arms can vary depending on the species and individual.

In short: The terms "nine-armed starfish" and "millipede starfish" refer to different things. There is no such thing as a millipede starfish.
