Highighted items on the list are where Chaenodraco wilsoni may be found.
Anmärkningar They are most common in shallower waters of the continental shelf, especially on banks less than 250 m deep in areas where local upwellings increase food supply (Ref. 6390). Aggregations of spiny icefish, which are believed to be feeding aggregations, have been observed over shallow banks in summer (Ref. 6390). The larvae spend their first summer in waters near the surface (Ref. 26875). Juveniles are also found near the surface, often in association with Antarctic krill (Euphausia superba) swarms (Ref. 6390).
