Hirudinea, commonly known as leeches, do not possess cilia. Instead, they have a smooth, segmented body covered with a cuticle, which allows for movement through contraction and relaxation of their muscles. While some annelids have cilia for locomotion or feeding, leeches primarily rely on their muscular bodies and suckers for movement and attachment.
What else can I help you with?
Why is clitellum necessary for oligochaetes and hirudinea but not necessary for polychaetes?
The clitellum is necessary for oligochaetes and hirudinea because it secretes a cocoon where the eggs are deposited and fertilized. It is not necessary for polychaetes because they typically have other methods of reproduction, such as external fertilization or larvae development in the water column.
Does Balantidium coli have cilia?
Yes, Balantidium coli have cilia. Balantidium coli is a ciliated protozoan parasite that uses its cilia for both motility and feeding.
What structure allow the paramecium to move?
Paramecium moves using hair-like structures called cilia. These cilia beat in a coordinated manner to propel the organism through its environment.
How are epithelial cell adapted for absorption of material?
cilia cilia is wrong. The correct answer is microvilli. cilia is more for movement

What is a leech's class?
Class Hirudinea.
What Class Does Leeches belong?
Leeches belong to the class Hirudinea, which is a subclass of the phylum Annelida. They are segmented worms known for their blood-feeding behavior.
What are the three classes of Phylum Annelida?
The three classes of Phylum Annelida are Polychaeta, Oligochaeta, and Hirudinea. Polychaeta are marine worms with bristles called chaetae, Oligochaeta include earthworms with few chaetae, and Hirudinea are leeches that are mostly freshwater and have suckers for attachment.
What is the taxonomy of a leech?
Kingdom Animalia, Phylum Annelida, Subphylum Clitellata, Class Hirudinea.
What is an example of a Hirudinea?
The medicinal leech (Hirudo medicinalis) is a well-known example of a Hirudinea. It is a blood-feeding annelid worm commonly used in medical procedures to assist with blood flow and reduce swelling.

What is the plural for cilia?
The plural for cilia is still cilia.
Do potato have cilia?
No plants have cilia.
What are the three classes of annelids?
The three classes of annelids are Polychaeta (marine worms with bristle-like structures called chaetae), Oligochaeta (terrestrial and freshwater worms like earthworms), and Hirudinea (leeches, which are typically found in freshwater environments).
Why is clitellum necessary for oligochaetes and hirudinea but not necessary for polychaetes?
The clitellum is necessary for oligochaetes and hirudinea because it secretes a cocoon where the eggs are deposited and fertilized. It is not necessary for polychaetes because they typically have other methods of reproduction, such as external fertilization or larvae development in the water column.
