Table 2. Comparison of species-level assigned taxonomy from this study with previous records in Antarctica.
“Observed” indicates whether the species has been directly observed in the Antarctic region, while “eDNA” represents detection through environmental DNA analysis from samples such as seawater. The “Ross Sea” column specifies whether the species has been recorded in the Ross Sea region. “+” denotes presence, a “–” indicates absence, and “+-” indicates detection applicable to organisms of the same genus.
