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

Southwest Pacific: Solomon Islands and Australia. Records from southern Mozambique and Natal, South Africa are misidentifications of Hippocampus camelopardalis. 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)

In shallow, weedy inshore areas and Zostera seagrass beds; also on sponges. Also under jetties on holdfasts of kelp, and on other man-made structures such as shark nets. Diurnal and site faithful (Ref. 30915). 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

Gestation period 21-22 days depending on temperature (Ref. 30915). Monogamous and faithful to pair in the wild (Ref. 30915). Male carries the eggs in a brood pouch (Ref. 205).

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=0.00417 (0.00160 - 0.01085), b=3.00 (2.78 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming annual Fec<1000).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
Price category (Ref. 80766):   Unknown.
