Maturity: L_m ? range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 50894); 15.0 cm TL (female); common length : 9.7 cm TL male/unsexed; (Ref. 12193)

Short description Identification keys | Morphology | Morphometrics

Slender, elongate fish with elongate jaws forming a prominent pointed beak. Scales very small and numerous (Ref. 26938).

Occurs in weedy canals and tolerates poorly oxygenated waters and salinity to 40 ppt. Occurrence in saline (34-37 ppt.) water in Florida seems to be a case of local acclimatization. Formerly used in medical research. Total length 14 cm (Ref. 26938). Mostly freshwater, sometimes brackish (Ref. 26938). Piscivore (Ref. 79012).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00415 - 0.01592), b=3.16 (2.99 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
