There are between 9000-12400 species of these segmented worms, including the common earth worm. The body plan is divided into repeating segments, separated by thin membranes called septa. This repeating body plan is called metameric.

The annelids (also called "ringed worms"), formally called Annelida (from Latin anellus "little ring"), are a large phylum of segmented worms, with over 17,000 modern species including ragworms, earthworms and leeches.
From water snails (Potamopyrgus), amphipods, earthworms (Annelida), bullies (Gobiomorphus spp. and Philypnodon spp.) to small fish including trout (Oncorhynchus spp.) and perch (Perca fluviatilis) (Jellyman, 1990).
Examples include fungi, snails and slugs (Gastropoda), insects (Insecta), spiders (Arachnida), centipedes (Chilopoda), millipedes (Diplopoda), earthworms (Annelida), carrion, and vegetation [10,23,48,71,74].
The most familiar and appreciated kind of worm to gardeners-and anyone who likes to play in the dirt-are earthworms, members of phylum Annelida, as are thousands of species of marine worms and leeches.
A Worm is an elongated soft-bodied invertebrate animal. The best-known is the earthworm, a member of phylum Annelida, however, there are hundreds of thousands of different species that live in a wide variety of habitats other than soil.
Earthworm is the common name for the larger members of the Oligochaeta in the phylum Annelida. Folk names for earthworm include "dew-worm", "night crawler" and "angleworm".
The major invertebrate phyla are porifera (sponges), platyhelminthes (flatworms), nematoda (round worms), annelida (earthworms, marine worms and leeches), cnidaria (jellyfish, coral and sea anemones), mollusca (octopus, nautilus, squid, slugs, ...
