Platyhelminthes or flatworms are endoparasites found in animals. Fasciola (liver fluke), Taenia (tapeworm), etc. are examples of flatworms.

Aschelminthes have a body with a circular cross-section and are hence known as roundworms. These include Ancylostoma (hookworm), Ascaris (roundworm), etc.

Annelida includes organisms whose body is divided into segments called metameres. Hirudinaria is a blood-sucking leech which belongs to the phylum Annelida.

Arthropoda is the largest phylum, and it mainly includes insects. Locusta or locust is an example that is a gregarious pest.
