Thanks for the pictures, Baja. I don't grow houseplants, but I might have to try one of these sometime.
Evan, Yes, it does look like an arm crest but very thick, with multiple new heads along the ridge. Each head will try to grow in diameter, correct? but they will crowd each other. What happens as this structure gets bigger? Do one or two dominant heads take over and the others give up and get overgrown? Do the heads eventually fall off and start new plants?
