What else can I help you with?
An earthworm uses its setae to?
The setae, or hair-like projections from each segment, help the earthworm anchor into the soil when burrowing and moving through the dirt. Without the help of the setae, a worm would have a harder time gaining enough traction to pull itself forward.
What direction do setae point?
The setae point backwards. They cling to the surroundings of the worm as it contracts its muscles to pull it along. They are what makes pulling an earthworm straight out of the ground difficult. Think of them as little hooks.
Are the setae on an earthworm segment paired?
Yes, the setae on an earthworm segment are usually arranged in pairs, with each pair located on opposite sides of the segment. These setae help the earthworm grip the soil and aid in movement.
Why do you think that the maxillipeds are fringed with hair like structures called setae?

What helps an earthworm dig through the soil and where is this located?
An earthworm's ability to dig through soil is aided by its strong, muscular body and the hydraulic pressure created by its body fluids. The earthworm's setae, tiny bristle-like structures on its body, also help it grip onto soil particles as it moves. These structures are located along the earthworm's body segments.
What direction do setae face on an earthworm?
Setae on an earthworm (an annelid) point backwards to add traction as it moves, especially if it is moving up soil or something. Think of it as hooks, essentially a source of friction, for the generally smooth worm as it moves using peristaltic motion.

Yes, the setae on an earthworm segment are usually arranged in pairs, with each pair located on opposite sides of the segment. These setae help the earthworm grip the soil and aid in movement.
What structures help an earthworm move through the soil and where are they located?
The Setae, located on the underside of the worm.
How does the setae help the earthworm adapt?
Well the setae is what allows earthworms to move thorugh the dirt and stuff :)
When an earthworm moves what structures allow it to hold on to the soil?
Setae
What type of skeleton helps and earthworm to move?
earthworm moves by the hair like projections called setae .
How do bristles help the earthworm in its movement?
Bristles also known as setae. They work as legs; they grip to soil with the setae. Setae also can dig through soil.
What does a setae on a earthworm do?
Setae are bristles or hair-like structures that help attach the earthworm to the ground and create friction so if an earthworm is going down a hill, it would slide down but actually continue to move through hydrostatic pressure.
Which structures help the earthworm grip the ground as it moves?
RRERFEAAF
What do the bristles on the underside of the earthworm's body do?
The bristles along the body of an earthworm are called the Setae, they are used as anchors as the earthworm moves along. The earthworms will anchor the rear of the body as it extends the front then anchor the front of the body as it contracts the rear. The setae are extended and contracted in sequence to match the movement of the body.
