Morphology | Morphometrics
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.
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).

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=0.00676 (0.00242 - 0.01892), b=2.93 (2.69 - 3.17), 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) .
