Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 9806); common length : 20.0 cm TL male/unsexed; (Ref. 9661)
Inhabits deep coastal slopes and sheltered muddy substrates, usually in deep water offshore, but occasionally shallow near seagrass beds with silty rubble substrates (Ref. 48637). Usually occurs in sandy bottoms in coastal waters. Solitary (Ref. 90102). Feeds on benthic invertebrates. Generally considered as trash fish; not consumed. Its flesh and organs are poisonous (IUCN, http://www.iucnredlist.org/details/154933/0) however,
