ahermatypic1933

1933 J. W. Wells in Bull. Amer. Paleontol. 18 109 The term hermatypic, from herma, a reef, is therefore proposed to describe corals of the reef-building type, the living species of which possess symbiotic zooxanthellae within their tissues. In contrast to this term, ahermatypic is proposed to describe the corals of the non-reef-building type, the living forms of which do not possess zooxanthellae.

1967 Oceanogr. & Marine Biol. 5 455 One may point to the flourishing Quaternary population of deep-water ahermatypic corals.

2009 C. R. C. Sheppard et al. Biol. Coral Reefs ii. 42 Most species that have adopted this system are ahermatypic.
