Examples

“Rhizosessile forms. - Several ketophyllid, cystiphyllid and operculate rugose corals are rhizosessile, characterized by having rhizoid (= rootlike) holdfasts which supplied secondary support⟳ to the corallites.”

“Rhizosessile genera have⟳ root-like holdfasts emanating from the corallite at several levels, and fastened to sediment grains (e.g. Dokophyllum).”

“The use⟳ of the spines to support⟳ the shell above the substrate and the mode of life has been discussed by Rohr and Packard (1984), who concluded that it was an adaptation for a firm substrate. The presence of the rhizosessile rugose coral Rhyzophyllum in the same beds suggests that other benthic taxa had adaptations to a soft substrate.”

“The rhizoid structures support⟳ the further growth of corals displaying a rhizosessile life strategy (sensu Neuman) and are typical of relatively large solitary corals living within soft-bottom environments. This type⟳ of attachment helps maintain⟳ a stable position, being connected to other embedded and stable hard particles.”
