Rhombozoa

Rhombozoa/Dicyemida
Scientific classification
Kingdom:	Animalia
Superphylum:	Lophotrochozoa
Phylum:	Rhombozoa van Beneden, 1876
Families
Conocyemidae Dicyemidae Kantharellidae

The Rhombozoa, or Dicyemida, are a group of tiny parasites that live in the renal appendages of cephalopods.

Classification is controversial.^[1] They are probably a new phylum. Traditionally, dicyemids have been grouped with the Orthonectida in the Mesozoa. However, molecular phylogeny indicates that dicyemids may be more closely related to the roundworms.^[2]
