Sexual dimorphism:

- Both Ascaris lumbricoides (intestinal roundworm) and Anopheles stephensi (mosquito) exhibit sexual dimorphism, where males and females have distinct physical differences.
- In the case of Ascaris lumbricoides, males are smaller and have a curved tail, while females are larger and have a straighter tail.
- Anopheles stephensi mosquitoes also display sexual dimorphism, with females being larger and having a longer proboscis for blood-feeding compared to males.

Hibernation:

- Both Ascaris lumbricoides and Anopheles stephensi are known to undergo a form of hibernation or dormancy to survive adverse environmental conditions.
- Ascaris lumbricoides eggs can remain dormant in the soil for extended periods until conditions are favorable for hatching.
- Anopheles stephensi adults can enter diapause, a form of dormancy, to survive unfavorable conditions such as cold temperatures.

Anaerobic respiration:

- Ascaris lumbricoides exhibits anaerobic respiration in its parasitic life stage within the host's intestines, where it can thrive in low-oxygen environments.
- Anopheles stephensi larvae also rely on anaerobic respiration in their aquatic habitats, as they do not have access to atmospheric oxygen until they reach the water surface to breathe.

Metamerism:

- While Ascaris lumbricoides displays metamerism in the form of a segmented body with repeated units, Anopheles stephensi does not exhibit this characteristic.
- Ascaris lumbricoides has a cylindrical body divided into distinct segments, each containing specific organs and structures.
- In contrast, Anopheles stephensi has a more uniform body structure without clear segmentation.
