Etymology: Harpagifer: Greek, arpagifer, grappling hook, robbery, voracoius (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal. Polar; 57°S - 67°S
Southern Ocean: along the Atlantic coasts of the Antarctic Peninsula, South Shetland, South Orkney and South Sandwich islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.5 cm SL male/unsexed; (Ref. 5191); max. reported age: 9 years (Ref. 5191)
Depth range: 0-5 m on rocky bottoms. Usually under rocks; rarely under algal fronds. A specialized feeder on amphipods, mainly Gondogeneia antarctica. Feed on small crustaceans and common in littoral of all sub-Antarctic islands (Ref. 42041). Iteroparous and devotes a lot of time to parental care (Ref. 5191). Larval pelagic phase is long (Ref. 71843).
