Similarly, what is the meaning of segmented worms? Segmented worms (phylum Annelida ) are so named because of their elongated, more or less cylindrical bodies divided by grooves into a series of ring like segments. Typically, the external grooves correspond to internal partitions called septa, which divide the internal body space into a series of compartments.
Similarly, what are three types of segmented worms?
Scientists have classified worms into more than 15 phyla. The phylum Annelida contains the segmented worms. Annelida is further divided into three subclasses: Oligochaeta, Hirudinea and Polychaeta. Thousands of species of segmented worms comprise these three subclasses.
What do segmented worms look like?
Segmented worms have long and narrow bodies made of many linked sections called segments. These worms also have a head end and a tail end, meaning they are bilateral symmetry. Some of the segmented worms look like flatworms and roundworms, which are: cylindrical bodies and jelly-like.
