Morphology | Morphometrics
soft rays: 2 - 3. Diagnosis: extremely elongate; tubular snout; tail shorter than head and trunk; body encased by bony plates or rings; 19-21 bony rings before, 22-24 behind, anus; anal and caudal fins present; dorsal fin beginning on trunk, extending mainly over tail; brood pouch of males on underside of trunk (Ref. 57226).
Occurs in coastal rivers, streams and estuaries (Ref. 4127). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Eggs are attached to a kind of brood pouch, formed by two skin folds on the belly of the male (Ref. 13371).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00054 (0.00024 - 0.00123), b=3.11 (2.92 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±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 (20 of 100) .
