Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; brackish; demersal; pH range: 6.0 - 8.0; dH range: 9 - 19; non-migratory. Tropical; 25°C - 37°C (Ref. 36880 ); 29°N - 11°N, 100°W - 79°W (Ref. 55262 )

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

North and Central America: Laguna San Julian, northeast of Ciudad Veracruz in Mexico to Costa Rica. Southern Gulf of Mexico, southern Yucatan and along Central American coast south to Nicaragua (Ref. 26938 ). Introduced in freshwater in Florida (Ref. 26938 ).

Size / Weight / Age

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 Morphology | Morphometrics

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

Biology     Glossary (e.g. epibenthic)

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 ):  PD 50 = 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).
