Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 4509)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 41-51; Anal spines: 0; Anal 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).

Biology     Glossary (e.g. epibenthic)

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):  PD50 = 0.5000   [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), in cm Total Length, 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) .
