Nematoda
The nematodes ( or ; ; ), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic. Parasitic worms (helminths) are the cause of soil-transmitted helminthiases.

Flabelligera
Flabelligera is a genus of polychaetes in the family Flabelligeridae. Species are common around the world, in both temperate and cold waters. Flabelligera species have long, club-like papillae, which are encased in a smooth mucus sheath. They also have a distinct cephalic cage (a fan-like arrangement of chaetae around the head), and hooked neurochaeatae (ventral chaetae) which they use to hold onto rocks.
