Nem split...

[MERKEY]

I've seen others here have them split but never one of my own....I'll try to get more/better pics but is this the start of a plit?

Looks like there are 2 mouths now. It's been retracted for half the day and then came out like this....

Any chance you can see the foot? I have had BTA's split and usually a new mouth forms post-split. Generally if the nem is splitting you will see the foot start to stretch significantly from two points.
