Animal Diversity

Nematodes are commonly known as roundworms. They are free-living, very tiny organisms. They have an elongated and tubular body. These organisms have a nervous system and are mostly act as parasites to both animals and plants.

Platyhelminthes

Platyhelminthes are also known as "flatworms" because as they are dorsoventrally flattened from head to tail. They are invertebrate, soft-bodied, acoelomate, unsegmented and have bilateral symmetry.
