What is the clitellum function?
The clitellum is a thick, saddle-like ring found in the epidermis (skin) of the worm, usually with a light-coloured pigment. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. The main function of clitellum is cocoon formation.
Which number is the clitellum?
The clitellum forms a band that can be flared, non-flared, saddle-shaped, or annular. It is generally found between segments 26 and 33. The clitellum is only found on adult worms.
Why is the clitellum so important?
The number of the segments to where the clitellum begins and the number of segments that make up the clitellum are important for identifying earthworms. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids, such as leeches.
What is Prostomium in zoology?
The prostomium (From Ancient Greek, meaning “before the mouth”; plural: prostomia; sometimes also called the “acron”) is the cephalized first body segment in an annelid worm’s body at the anterior end. The prostomium together with the peristomium, which includes the mouth and pharynx, make up the annelid head.
What is the function of the clitellum in an earthworm?
Explanation: The clitellum is a thickened glandular and non segmented section of the body wall near the head of the earthworm that secretes a viscid sac in which the eggs are deposited. The clitellum is part of the reproductive system of earthworm. It also secretes a viscous fluid to form a cocoon for it’s eggs.
How is the clitellum used in sexual reproduction?
To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids, such as leeches. In earthworms, the clitellum can only be seen when the worm is sexually mature.
What is the function of the clitellum in annelids?
The clitellum is a thick, saddle-like ring found in the epidermis (skin) of the worm, usually with a light-colored pigment. To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids. Keeping this in consideration, what is function of Clitellum in Oligochaetes?
What kind of fluid does the clitellum secrete?
To form a cocoon for its eggs, the clitellum secretes a viscous fluid. This organ is used in sexual reproduction of some annelids. In earthworms, the clitellum can only be seen when the worm is sexually mature. It may be white, orange-red or reddish-brown in colour.
