During mating, two earthworms exchange sperm with each other. Each worm has a clitellum, a thickened band that produces a mucus sheath to protect the fertilized eggs. This exchange allows both worms to have a supply of sperm for fertilization, increasing genetic diversity in their offspring. After mating, each worm can fertilize its eggs using the sperm received from its partner.

What do two earthworms exchange during mating?
During mating, earthworms exchange sperm and eggs. The exchange occurs through a process called copulation, where the two worms line up ventral to ventral and exchange gametes. This exchange allows for fertilization to occur internally within the worms' bodies.
Do earthworms have a placenta?
Nope - Earthworms are hermaphrodites - in that they have both male and female reproductive organs. During mating they exchange sperm - and lay eggs a few days later which hatch into tiny earthworms.
Does an earthworm have to produce sperm and egg for fertilization to occur?
No, earthworms are hermaphrodites, which means they have both male and female reproductive organs. They can produce both eggs and sperm, and fertilization can occur when two earthworms exchange sperm during mating.
Do earthworms mate for life?
No, earthworms do not mate for life. They reproduce sexually by copulating with another earthworm in order to exchange sperm. After mating, each earthworm goes its separate way to continue its activities.
What is Sexual orientation of earthworms?
Earthworms are hermaphroditic, meaning each individual possesses both male and female reproductive organs. They can produce both sperm and eggs, allowing them to mate with other earthworms to exchange sperm and increase genetic diversity. During mating, earthworms align their bodies and exchange sperm, which can later be used to fertilize their own eggs. This unique reproductive strategy helps ensure the survival and adaptability of earthworm populations.
Where is navel of earthworm present?
It doesn't have one ! Earthworms are hermaphrodites - possessing male and female reproductive systems. During 'mating' they exchange sperm with each other. Subsequently, they both lay eggs which develop into tiny worms.
Why snakes and earthworms are kept in different groups?
Because they are completely unrelated animals ! Snakes have a skeleton composed of hundreds of individual bones... Earthworms have no skeleton at all. Earthworms are vegetarians - Snakes are carnivores. Earthworms are hermaphrodites. They possess both male & female reproductive organs. During 'mating' two worms simply exchange sperm with each other - Snakes need to mate with another snake of the same species but opposite gender in order to reproduce.
What is special about earthworms reproductive system?
Earthworms have a unique reproductive system that is hermaphroditic, meaning each individual possesses both male and female reproductive organs. During mating, two earthworms exchange sperm, which they later use to fertilize their own eggs. They produce a cocoon from a special gland, which contains the fertilized eggs and serves as a protective environment for the developing young. This reproductive strategy enhances their ability to reproduce in diverse environments.
What is the function of the clitcllum?
The clitellum is a thickened, glandular section of the body wall found in annelids, particularly earthworms. Its primary function is to produce mucus during reproduction, which helps to form a protective cocoon for fertilized eggs. The clitellum also aids in the alignment of mating individuals during copulation, facilitating the exchange of sperm.
Male genital pores in a earthworm?
Male genital pores in earthworms are openings located on the ventral side, typically found in segment 15 or 16, depending on the species. These pores serve as the exit for sperm during reproduction, facilitating the transfer of sperm to a mate during copulation. Earthworms are hermaphroditic, possessing both male and female reproductive organs, which allows them to engage in reciprocal mating. After mating, earthworms can produce cocoons containing fertilized eggs, ensuring the continuation of their species.
How do lions exchange gases?
by mating
The cuff like structure in earthworms used in reproduction?
The cuff-like structure in earthworms used in reproduction is known as the clitellum. During mating, the clitellum secretes a mucus that forms a cocoon around the eggs and sperm, eventually developing into a fertilized egg. This cocoon is then deposited in the soil, where the new earthworms will hatch.
