Hairworms - Nematomorpha

Long, thin wire-like worms found in damp or aquatic habitats. They are not segmented. They are typically 50-100 mm in length and 1-2 mm in diameter. Identifying this group to species is very difficult but we have included representative images below to illustrate the phylum.

Nematodes are similar and could be confused, though these are usually shorter in length and much more mobile.

Damp and aquatic habitats.
