Hammer pooping?

Have never been able to see my hammer mouth until he is doing this today …
Is he pooping?
I usually see the mucus coming out of it after feeding but not this

Oral cavities, the food comes in, energy is assimilated and then the waste goes out.

Can you imaging how much weight people might lose if they had taste buds at both ends of diggestive tract.
