Do worms drown?

Do earthworms fart?

Last year, a bunch of researchers listed which animals they studied farted. According to their list, it appears that some worms don't pass gas either.

Do worms have 2 brains?

In most annelids (segmented worms) such as the earthworm, two cerebral ganglia (bundles of nerve cells) form a primitive bilobed brain, from which sensory and motor nerve fibres lead to other areas of the body.

Does a worm have a brain?

Do worms have brains? Yes, although they are not particularly complex. Each worm's brain sits next to its other organs, and connects the nerves from the worm's skin and muscles, controlling how it feels and moves.

Do worms bite?
