Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 20 - 200 m (Ref. 7366), usually 20 - 50 m (Ref. 7366). Tropical
Eastern Atlantic: mainly Congo and Angola, but probably further north.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 2683)
Burrows in sand and mud (Ref. 2683). While buried, it waits for its prey, attracting them by means of its appendage. Feeds mainly on fish (Ref. 5377).
