11. The hemal system ensures against endoparasites . 12. Larval stages of endoparasites often infect sites in the host other than the blood or gastrointestinal tract. 13. Another important adaptation of endoparasites is the gut, which digests host macromolecules into soluble utilisable products. 14. "' Tetradonematidae "'is a family of nematodes, most being endoparasites of arthropods. 15. Once inside the host, adult endoparasites need to shed offspring into the external environment to infect other hosts. 16. Many adult endoparasites reside in the host s gastrointestinal tract, where offspring can be shed along with host excreta. 17. In many such cases, larval endoparasites require their host to be consumed by the next host in the roundworms. 18. Those that live inside the host are called "'endoparasites "'( including all parasitic worms ). 19. The eyes and antennae of brachyceran larvae are reduced or absent, and the abdomen also lacks appendages such as endoparasites . 20. Due to the different strategies of endoparasites and ectoparasites they require different adaptations in order to acquire nutrients from their host.
