Short description Morphology | Morphometrics

Dorsal spines (total): 18 - 19; Dorsal soft rays (total): 9-10; Anal spines: 7-8; Anal soft rays: 6 - 7. This species is distinguished by the following set of characters: teeth properly incisor, even in young; caudal edge of mesethmoid with a unique shape; caudal edge of supraoccipital crest straight, inclined rostrad, its height 27% of postethmoid skull length; width of posterior premaxillary expansion greater than 41% of length of the same bone; arms of articular equal in length; gut S-folded ventrorostrally in adults, anal and medial loops nearly touching; with an abrupt, steep head profile (Ref. 74403).

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

Central America: Atlantic slope of Nicaragua and western Costa Rica, in the San Juan River drainage, including Lake Nicaragua and Lake Managua.

Biology     Glossary (e.g. epibenthic)

Inhabits both lakes and rivers. Proliferates in rivers with medium to high velocities. Found between 35 and 535 m elevation (Ref. 36880). Feeds on aufwuchs which cover rocks and submersed trees and filaments of algae.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec=50-60).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
Price category (Ref. 80766):   Unknown.
