Do worms have a pancreas?

Worms are invertebrates; not bugs.

A Plume worm is a feather duster worm which is a category of segmented worms.

They will not harm them; however they will not live on the food scrapes you are putting in your farm like the red worms will.

You can get them by letting the dog kiss you in the face.

There is such a thing as true worms. Some examples would be earth worms, red wrigglers, blood worms etc.
