Found in seafloors, well adapted to extremely low and stable temperatures (-1.86°C), annual mean temperature of McMurdo Sound) (Ref. 45168). Feed on polychaetes, gastropods, isopods, amphipods and few algae. Spawn once a year (Ref. 1071). Utilized for human consumption.

Life cycle and mating behavior Maturities | تولید مثل | Spawnings | Egg(s) | Fecundities | توزاد ( لارو)

Although members of this Family are known to tend to egg masses, it is assumed that because of the high fecundity, this species is a non-guarder (RF), to be corrected if direct information becomes available.
