Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
Indo-Pacific: Red Sea and East Africa through the Indian Ocean islands to western Australia, New Guinea, Philippines, and islands of Oceania. Not found in Hawaiian islands, and apparently absent from Indo-Malayan Archipelago. Has been mentioned in the literature under other names, particularly Hyporhamphus erythrorinchus and Hyporhamphus dussumieri (Ref. 10943).
Found chiefly around coral reefs (Ref. 58534) and islands but extends a little further from shore than Hyporhamphus (R.) dussumieri which has a similar range (Ref. 10943). Found in schools (Ref. 9710). Feeds on zooplankton and floating matter. Eggs covered with adhesive filaments to assist in attaching to floating and benthic objects (Ref. 43448).

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=0.00000 (0.00000 - 0.00000), b=0.00 (0.00 - 0.00), based on (Ref. 93245).
Trophic Level (Ref. 69278): 3.5 ±0.48 se; Based on food items.
Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100) .
