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

Eastern Indian Ocean: northwestern Australia only, from Torres Strait to North West Cape. Records from Queensland need verification; often misidentified with Hippocampus histrix. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.

Biology     Glossary (e.g. epibenthic)

Found in sheltered bays. Color varies from either white, orange or yellow with light patches and sometimes network of fine dark lines; also with narrow lines across snout. Ovoviviparous (Ref. 205), monogamous (Ref. 36642). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00565 (-0.21493 - 0.22622), b=2.95 (2.83 - 3.06), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 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 (22 of 100) .
Price category (Ref. 80766):   Unknown.
