How many brains does a worm have?

Answer 1

No one answer, since it depends on which worm.

Answer 2

Most worms, like earthworms, have a simple nervous system with a collection of ganglia that act like primitive brains. Earthworms have a cerebral ganglion, which functions like a brain, located near their mouth. So they have one main brain-like structure.

Answer 3

Worms are said to have five hearts, now I'm not sure about brains...they say maybe two or four.

Worms have no legs!!
