TABLE 5 in Morphological and taxonomic diversity of the bryozoan genus Chaperia (Cheilostomata: Chaperiidae) in the Aotearoa New Zealand EEZ and on the southern Norfolk Ridge

TABLE 5. Comparison of some major characters of described extant non-New Zealand species of Chaperia. Some metrics are not given in the original descriptions (e.g. Lamouroux, 1825), whereas some other metrics (e.g. OpL:ZL ratio, % of opesia bordered by spines) were able to be determined from the original illustrations 1 if the information was not originally provided in the text.
