They are native tunicates.

Either Corella willmerina or Corella inflata.

Agreed. Tim nailed it. Most likey they're Corella inflata since they're in a cluster like that.

But they're the good guys. :)

Oh, no eye, no spinal chord! What you're looking at is a digestive tract filled with poop! :) Really!!

Tunicates, aka Sea Squirts, aka Urochordates, are pretty complex and while they had a little spinal chord when they were larvae, called a notochord, it dissolved by the time they attached themselves to a rock and grew into an adult tunicate. They have an intake siphon, a complete digestive tract, and an outflow siphon too.
