the use of brain

From CONSCIOUSNESS EXPLAINED, by Daniel Dennett, p. 177

"The juvenile sea squirt wanders through the sea searching
for a suitable rock or hunk of coral to cling to and make
its home for life. For this task, it has a rudimentary
nervous system. When it finds its spot and takes root, it
doesn't need its brain anymore so it eats it! (It's rather
like getting tenure.)"
