In contrast, the larvae of the other reef corals, including Goniastrea aspera and Platygyra daedalea, and the ahermatypic coral Caryophyllia smithii, swim much faster, at about 25, 21, and 90 cm per 30 s, respectively (Tranter et al.
It consists of simple primitive ahermatypic diaphragmatophoral corals, the so-called Cyathaxonia fauna, and is represented in the sections studied by solitary corals bearing axial structures of different types (Flugel 1972, 1973).
Additionally some experiments in ahermatypic corals have demonstrated that a competitive dominant may influence the abundance and population structure of a subordinate by reducing its sexual reproductive output, increasing larval mortality and altering recruitment patterns (Chadwick.
