Labeled features include actinopharynx (A), endodermal marginal musculature (EMM), lacunae formed by dissolution foraminifera tests (L-FT), mesogleal marginal musculature (MMM), oral disk (OD), peristome (P), tentacles (T); measurements of capitular tissue width made at black arrow. A. Longitudinal section of contracted polyp at capitulum showing endodermal portion of cyclically transitional marginal musculature. B. Longitudinal section of contracted polyp at capitulum showing mesogleal portion of cyclically transitional marginal musculature. C. Longitudinal section of contracted polyp.
