Need more clues. Was it a "wet" creature or a dry creature? Did it have any legs or no legs? What was its approximate size?

I have these worms all over my back porch they are just like a worm only bright yellow and dry out on the concrete just like a worm what are they.

Hi I am on the West Coast of TAS and have found these (exactly like the picture) in my gardens are they good bad and are they a worm at all
