Table 1 (continued on next page). Coordinates and basic data on sampling stations, species identities of Condyloderes Higgins, 1969, Echinoderes Claparède, 1863, and Polacanthoderes Sørensen, 2008, type status, and catalogue numbers. The list only includes stations with adult specimens, and juveniles of Echinoderidae are not listed. Study sites in Andvord Bay refer to: IBB = Inner Basin B; MBA = Middle Basin A; and OBA = Outer Basin A.
