Spiral musculature of Chromadorida. CLSM micrographs. Buccal dilators in brown, somatic muscles in blue, spiral musculature in green. Anterior to the left (a) Chromadorina sp. Anterior pharynx. (b) Chromadorina sp. Posterior pharynx. (c) Paracyatholaimus sp. Pharynx area (d) Pomponema sp. Posterior pharynx. (e) Synonchiella sp. Posterior pharynx. (f) Marylynnia sp. Posterior pharynx area.
