海; 新鮮な水; 汽水性の pelagic-neritic; 両側回遊性; 深さの範囲 0 - ? m. Subtropical
Northwest Pacific: Honshu, Japan and the northern part of the Yellow Sea south to southern China, including Taiwan. Reports from Ryukyu Islands do not seem to be supported by specimens and may represent misidentifications. However, all of Gushiken's Okinawa photographs (except the one labeled Hyporhamphus intermedius) seem to be correctly identified.

Estimates based on models
Phylogenetic diversity index (参照
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00186 (0.00120 - 0.00290), b=2.96 (2.83 - 3.09), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
栄養段階 (参照
69278): 3.4 ±0.45 se; based on food items.
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (参照
