Ascaris is the parasitic worm. It is also known as human infection. They are not found in aquatic medium, they are mostly found in soil. Sexual reproduction occurs in these organisms. Male and female reproductive parts are present in different organisms.

Complete answer:
Ascaris includes soil transmitted helminths that are also called parasitic worms. Ascaris lumbricoides is the pathogen of ascaris. Ascaris has been present in humans for many years. They were found in the intestine of the mummified humans. It lives in the intestine of the humans and ascaris eggs are passed in the feces of the infected person. Maturation of eggs occurs outside the body and becomes infectious. Infection spread by ingesting the ascariasis eggs. Pig roundworm (Ascaris suum) can also infect humans.
Ascaris' body is long, cylindrical, and fusiform. Wall of the body is composed of cuticles. Pseudocoelom is present in them. They respire through simple diffusion. Nerve ring is present in the longitudinal nerve cords. Sexual reproduction occurs in ascaris. Males are shorter than females.
Ascaris is not an aquatic or living in fresh water bodies as they cannot survive there. ascaris can be either male or female. So, they are called as unisexual.
