The sea squirt uses its nervous system early in life to move around and find a suitable rock to attach to; once attached and sedentary, movement is no longer necessary for survival, so the sea squirt digests its brain for energy.

Evidence Quote

Early in its life, the sea squirt has a nervous system. It will use this nervous system to move around and find a suitable rock to attach itself to, then it will spend the rest of its life there. At that point, movement is no longer a necessity for survival, so the very first thing the sea squirt does is it digests its brain for energy.
