Details about some more phyla of invertebrates:

Annelids, Nematodes, Molluscs.

1. Phylum Annelids

Annelids are worms, with bodies made up of ring-like segments. Most of
them live in water, some like the earthworm live in moist soil.

2. Phylum Nematodes

Nematodes are worms, but unlike annelids their bodies are not divided into
segments. They are usually white, long and thin. They live in many different
habitats. Many nematodes live in the soil.
