"Sea Squirts that Eat Their Own Brains"

Sac-like creatures that latch onto
coral and filter their food from
... sea water, sea squirts are
hermaphroditic, producing
tadpole-like larvae that disperse
to find new homes on which to
grow. At this larval stage, sea
squirts have the same anatomical
characteristics as fish, birds,
reptiles and mammals, but as they
grow, they lose their minds –
literally. They digest their own
cerebral ganglia, which controls
movement, because once they’re
sedentary, they no longer need it.
