Which major geographic area primarily defines the constrained distribution of C. daedalma?
Answer
Waters primarily around Japan, including the Ryukyu and Ogasawara Islands.
The Wrought Iron Butterflyfish is noteworthy for having a significantly restricted geographic range, making it a biogeographical anomaly compared to many widely distributed butterflyfish species. Its distribution is primarily concentrated in cooler, deeper waters associated with the Japanese archipelago. Specifically, its known habitat includes the waters directly surrounding Japan itself, extending south to include the Ryukyu Islands and the Ogasawara Islands. This limited spatial occupation suggests high specialization to the specific, cooler environmental conditions prevalent in that sub-tropical or temperate region.
