Earthworms

segmented worms

Earthworms have a reproductive system that is classified as hermaphroditic, meaning each individual possesses both male and female reproductive organs. They have specialized structures called clitella, which play a key role in reproduction by secreting a mucus ring during mating, allowing for the exchange of sperm. After mating, the clitellum also forms a cocoon where fertilization occurs and the eggs develop. This unique reproductive strategy allows earthworms to effectively reproduce in varying environmental conditions.

The excreta of an earthworm is called "cast" or "vermicast." This organic matter is rich in nutrients and beneficial microorganisms, making it an excellent natural fertilizer for soil. Earthworm casts enhance soil structure and fertility, promoting healthy plant growth.

no, because earthworms are very dirty, and that will lead to your lizards dying or being very sick. good luck! -_-

Yes, earthworm respiration is referred to as cutaneous respiration because they exchange gases directly through their skin. Their skin must remain moist to facilitate the diffusion of oxygen and carbon dioxide, as they lack specialized respiratory organs like lungs or gills. This process allows them to absorb oxygen from the environment and release carbon dioxide efficiently.

Earthworms are sensitive to a variety of stimuli, primarily light, moisture, temperature, and chemicals in their environment. They possess light-sensitive cells that help them avoid bright conditions, as they prefer dark and moist habitats. Additionally, they can detect vibrations and changes in soil composition, which aids in their movement and foraging. Their sensitivity to chemicals allows them to locate food sources and navigate their environment effectively.

It is seven (7) centimeters.

The earthworm's crop and gizzard feel different because they perform two different functions. The gizzard is hard to the touch because it is used to grind the soil the earthworm takes into its body. The crop is soft and more saclike because it stores food that the earthworm separates from the other things it takes in.

Earthworms do not have a skeleton at all.

Annelids include segmented worms including ragworms, earthworms leeches ,neries and fanworms.

Earthworms are mostly saprophytic in nature. They eat soil which inturn provides them with the dead decaying organic matter inside the soil.

No, it doesn't have six legs or more so it can't possibly be an insect.

Annelidia (Latin), or Annelid (English)
