Guess whether starfish have a brain? Starfish do not have brains, but they have nervous systems. For example, if a sensor nerve on one arm detects food, then this arm will become the main arm, thereby commanding and controlling other parts of the body to hunt for food. Isn't it amazing?

No
Answer: No
Starfish don't have brains. Although starfish don't have brains, they do have a nervous system. If the sensor nerve in one of the arms detects food, then that arm becomes the dominant arm and essentially controls the rest of the body.
