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

North America: Rio Nautla, northern Veracruz, Mexico, along the Atlantic slope of Campeche, Atlantic drainage of inland Mexico in the states of Oaxaca and Chiapas, presumably across the base of the Yucatan Peninsula to Quintana Roo, south to southern Belize (Moho river drainage). Also found in the Rio Usumacinta drainage in Guatemala, and in isolated islands in the Petén region.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 2.6 cm SL male/unsexed; (Ref. 30499); 3.5 cm SL (female)

Biology     Glossary (e.g. epibenthic)

Usually found near the shore where vegetation is present in both pond and river habitats. Feeds mainly on benthic, vegetation-associated invertebrates, and on terrestrial shoreline organisms.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

After about 28 days gestation, female gives birth to 10-35 young. Sexual maturity is reached after four months (Ref. 2060).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00456 - 0.02295), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
