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).

Estimates based on models
Preferred temperature (Ref. 115969
): 19.2 - 27.9, mean 25.8 °C (based on 76 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00181 - 0.01153), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.73 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (35 of 100) .
