Etymology: Gunterichthys: Because of Albert C. L. G. Günther, German ichthyologist, 1830-1914 (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 0 - 9 m (Ref. 34024). Subtropical; - 24°N
Western Atlantic: northern Gulf of Mexico.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm TL male/unsexed; (Ref. 7251)
soft rays: 41 - 52;
Vertebrae: 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).

Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00174 - 0.01147), b=3.10 (2.87 - 3.33), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Vulnerability (Ref. 59153
