What zone category often describes the habitat at the 100 meter depth limit for C. daedalma?
Answer
Upper mesophotic reef environment
The lower boundary of the Wrought-iron Butterflyfish's habitat, documented at 100 meters, places it specifically at the outer edge of the photic zone. This depth range is frequently categorized in marine science contexts as the upper mesophotic reef environment. This zone is characterized by significantly diminished light penetration compared to shallower waters, indicating that the fish has adapted to conditions where sunlight is faint, contrasting sharply with the habitat of many other butterflyfish species that rarely descend below 30 meters.
