Vermeology

Vermeology (from Latin vermes, worms) is the field of biology dedicated to the study of worms. A person who studies vermeology is referred to as a vermeologist.

The umbrella term "vermeology" has fallen out of common use, as the animals known as worms belong to multiple phyla that are not closely related. Subfields of vermeology include nematology, the study of nematodes, oligochaetology (also called lumbricology ), the study of earthworms, and helminthology, which focuses on parasitic worms, also known as helminths. The field of malacology was also historically included within vermeology.

Works
The final book that Charles Darwin published in his lifetime focused on bioturbation by earthworms.
