No. Whilst most animals have a brain, there are many that only have a small central nervous system that has no real locus that could be called a brain. Single celled organisms are a prime example as are some microscopic marine life. There are also animals that have no central nervous systems, such as oysters, and some that have no nervous systems at all. All mammals have a brain however.

∙ 13y agoNo. Most do but not every animal does. Star fish, jellyfish and sponges do not have brains. The nervous system of the starfish is very simple, there is no brain, the nervous system is characterized by a nerve ring that surrounds the mouth. The nervous system of the the jellyfish is characterized by a series of interconnected nerve cells (a nerve net).
