Morphology | Morphometrics
soft rays: 2 - 3. Diagnosis: extremely elongate; tubular snout, which is short, ratio head length/snouth length 2.1-2.8; tail longer than head and trunk; ratio SL/head length 8.4-10.8; body encased by bony plates or rings; 12-13 rings before, 31-37 behind, anus; dorsal-fin origin above anal fin, either on last ring of trunk or on first ring of tail; pelvic fins absent; 12-15 pectoral-fin rays; anal fin strongly reduced, with 2 or 3 rays; 9 caudal-fin rays; brood pouch of males on underside of tail (Ref. 57226).
Adults occur in coastal rivers and streams (Ref. 4127), and swamps (Ref. 57226). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00049 (0.00022 - 0.00110), b=3.10 (2.91 - 3.29), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
