Dorsale zachte stralen (totaal) : 60 - 71; Anale zachte stralen: 41 - 52; Wervels: 38 - 40. Diagnosis: Blunt snout; small distinct eyes, 1.4-1.9% SL in adults; head naked, body covered with imbricate scales; interorbital in adults 5.6-7.7% SL; posterior infraorbital pores 2; rays in dorsal fin 60-71, anal 41-52, caudal 12-15; otolith with fused colliculi; sulcus small; 1 pair of pseudoclaspers with 2 almost equally long supporters (Ref. 55786).
Burrows in soft mud bottoms at shallow depths (0.7-6 m) of quiet lagoons, backwaters and saline parts of estuaries (Ref. 7251, 55786). Reported to give birth to very few, about 15 mm long juveniles in each clutch; one female found to have four 5-8 mm long embryos and has a 3.2 mm bivalve in the intestine (Ref. 55786). Probably common where it occurs (Ref. 34024).

Estimates based on models
Preferred temperature (Ref.
123201): 23.3 - 26.8, mean 24.6 °C (based on 124 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming Fec < 100).
Fishing Vulnerability (Ref.
