Intertidal bryozoans from coral reef-flat rubble Sa'aga, Western Samoa

摘要: Abstract A study of the major cryptofaunal species from reef-flat rubble (slabs and small boulders) at Sa’aga, Upolu Island, has yielded 10 Bryozoa (2 new), with following colonial morphologies: “two-dimensionally” encrusting— Puellina sp.; Calyptotheca mortoni n. sp., fixed-erect—Reteporellina samoensis Triphyllozoon rooted-articulated—Crisia elongata, Nellia tenuis, Chlidonia pyriformis; Savignyella lafontii; Vasignyella otophora; Margaretta gracilior. Systematic rearrangements include placing in Quadricellariidae, Savignyellidae superfamily Catenicelloide otophora is made type anew genus Vasignyella. dominate numerically over other suspension feeders this habitat. Much central portions undersides are occupied by bryozoans, surrounded sponges ascidians, periphery dominated crustose-coralline algae. Rooted, flexible can be so numerous as to form a turf. This t...
