Earthworms
They do not need them for locomotion. Besides, limbs that stick out on the sides are a hindrance when you are tunnelling.
The whisker-like structures on worms are called "setae." These tiny bristle-like appendages help worms with traction and movement through soil and other substrates. In some species, setae can also aid in anchoring the worm during locomotion.
Setae in annelids are stiff bristles present on the body. They help for example earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs are what make it difficult to pull a worm straight from the ground. (finzio liflio)
Ever seen one? No, some might have bristles though..that are tiny projections made for locomotion
The abdomen region of a grasshopper consists of the wings, tympanum, spiracles, and two pairs of legs. The wings, tympamnum, spiracles, and legs are used for locomotion of the grasshopper.
There are several sentences that the word locomotion can be used in. One sentence is; The steam locomotion was late to the depot.
Marine worms in the phylum Annelida are commonly referred to as polychaetes. These segmented worms are characterized by their bristle-like structures called chaetae, which aid in locomotion and anchorage in their marine environments. Polychaetes exhibit a wide variety of forms and habitats, often playing crucial roles in marine ecosystems. Examples include species like the ragworm and sandworm.
There is no such thing as a locomotion platypus.

Annelid worms have a hydrostatic skeleton that helps them move and maintain their body shape. They also regulate their body functions through nerve ganglia located along their ventral nerve cord, which control activities like movement, feeding, and reproduction. Additionally, annelids have specialized structures like setae that aid in locomotion and burrowing.
