Setae are small hairlike structures. You can find them on insects and most annelid worms (earthworms (use them to avoid being pulled from their tunnels), but also large marine worms that may look nothing like worms - try finding a picture of a sea mouse). However, they can be microscopically small, and at this size they're also found on the feet of geckos, for example, helping them stick to vertical surfaces!

What are earthworm bristles called?
The setae are small spines which are projected from the body wall by muscles to act as anchors in the surface that the worm is moving along. The muscle can also retract the setae The circular muscles contract and expand in co-ordination with the longitudinal muscle in series such as that if the posterior muscle are expanded and the anterior circular muscles are contracted the worm pushes and stretches its front end forward. The anterior muscles then expand to anchor its front end by use of the setae and the rear end is pulled forward. All this happens in a smooth and rhythmic motion.
What is meant by penial setae?
Penial setae refer to the sperm ducts of invertebrate animals. Penial setae are bristle-like structures on segmented invertebrates such s worms. They are usually located behind the worms' prostates.
