Etymology: Gymnodraco: Greek, gymnos = naked + Greek, drako = dragon (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 550 m. Polar; 61°S - 78°S
Southern Ocean: Antarctic Peninsula, South Shetland Islands and the Antarctic continental shelf. Probably circum-Antarctic, but no records yet from West Antarctica.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 34.0 cm SL male/unsexed; (Ref. 5192)
Adults spawn during September in Adélie Land. Hatching probably occurs in spring (mid-November) and pelagic development probably ends in autumn (February and March). Food items: fishes, amphipods, fish eggs and polychaetes (Ref. 5192). Larval pelagic phase is short (Ref. 41551).
