Two mouths on a yuma normal?

[I_Got_Crabs]

One of my yumas looks to be growing a second mouth (middle left of pic). The only kind of reproduction I've seen from them so far is sending off babies from their base.... Is splitting like this also normal?

I believe I have seen in videos that they have multiple different ways of splitting and repriducing.
