Reproductive System: Nematodes reproduce primarily through sexual reproduction. Reproductive structures in females include two ovaries, two uteri, a single vagina, and a genital pore that is separate from the anus. Reproductive structures in males include testes, a seminal vesicle, vas deferens, and a cloaca.Click to see full answer. Keeping this in consideration, do nematodes have a reproductive system? Nematode Reproductive Structures This is because the females are charged with producing large amounts of eggs, so they need a larger body to do so. Male nematodes on the other hand have one or two testes and a spicule, which is a long structure used during mating that injects sperm into the female’s reproductive tract.Secondly, do nematodes lay eggs? All nematodes lay eggs. Syngamy, or cross fertilization, is common in most nematodes. Hermaphroditism also occurs, with the nematode gonads producing spermatozoa first and storing them until the eggs are produced. Parthenogenesis is also a normal means of reproduction in some nematodes. Also, how does Ascaris reproduce? Once back in the small intestines, Ascaris worms mature into fertile adults, the females of which can each lay up to 200,000 eggs per day. These eggs are expelled by the host via feces, and the growth and maturation cycle begins again.How do phylum Nematoda eat?Fungal-feeders feed by puncturing the cell wall of fungi and sucking out the internal contents. Predatory nematodes eat all types of nematodes and protozoa. They eat smaller organisms whole, or attach themselves to the cuticle of larger nematodes, scraping away until the prey’s internal body parts can be extracted.
