Short answer: jellyfish or various small insects. If you want a deeper answer, it depends on what you call a brain because a jellyfish has a nerve cluster which is technically a giant brain and the insects without brains have what we call: ganglia it is basically a brain just with no ability to think abstractly; it just controls basic functions and instincts.

Portuguese man-o'-war, also known as the bluebottle, it has no brain and no heart and it cannot see.
a person can not function without a brain so no a person would not be able the talk without a brain the brain is connected to the spinal core with is almost connected to all of the bones in the whole human and animal body the brain in something that you need if something happens to your brain you could die that's why every one wears a helmet when biking and roller blading and other sports that could be dangerous so i would say no a person can not live or talk without a brain.ANS2:Many politicians do.
No! Michael Jackson did not get buried without his brain. Sometimes when people die, the doctor needs to know why or how a person died, so they take what they call a tissue sample of a person to find out why or how they died.
