An example of annelids are earthworms. They are segmented worms, and is the segments and what separates them (septa) that are largely responsible for locomotion. Movement occurs through a series of constriction and relaxation of the muscles along the worm. This is called peristalsis, and is how food travels down the esophagus after you swallow your food.
In addition to peristalsis, some worms have "hairs" (called chetae) along their bodies. They provide traction for the worm's body which is required for the worm to move. They can also be used to grip onto the soil if a predator such as a bird attempts to pluck it out of the ground.
Nerve-activated muscles are how nematodes move.
Specifically, the roundworm in question (Nematodaphylum) has a cuticle-covered epidermis (skin) over muscles controlling movement. The muscles lie lengthwise, not widthwise. The back's dorsal nerve and the belly's ventral nerve will activate the muscles when the nematode needs to effect thrashing locomotions while lying on one side.

Which of the three classes of annelids has suckers as an adaptation to it's way of life?
Leeches are the class of annelids that has suckers. They use these to suck the blood out of humans and animals in order for them to survive.
What did segmentation first arise in the annelids as an adaptation for?
Segmentation first arose in annelids as an adaptation for improved flexibility and movement. It allows for more specialized and efficient movement of the body, as each segment can move independently. Segmentation also allows for better control over body functions and increased survival capabilities.
