What is this nasty this??

[jason604]

I just bought a wild caught acro colony today from JL and while transitioning it to my tank I gripped what I thought was its skeleton and it squirted water right to my face. Like what!! Acro squirting water? So I took a closer look and it appears to be something that resembles a dried date. Each time I pressed on it it would squirt water out pretty dam far. Anybody have any idea what the hell this is and if I should cut it off my acro? Its now in my tank. Bottom right of the pics
