Actinopteri (ray-finned fishes) > Beloniformes
(Needle fishes) > Hemiramphidae
Etymology: Hyporhamphus: Greek, hypo = under + Greek, rhamphos = beak, bill (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - ? m. Temperate
Southwest Pacific: restricted to New Zealand, including the Chatham Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.0 cm SL male/unsexed; (Ref. 10988); common length : 22.0 cm TL male/unsexed; (Ref. 9258)
soft rays: 17 - 20;
Vertebrae: 55 - 58. Gill rakers usually 32 or less on the first arch and 25 or less on the second arch. Relatively longer upper jaw (usually longer than wide) and lower jaw (usually longer than head length), especially at larger sizes.
Occurs in inshore waters. Forms schools for spawning during mid summer (Ref. 9258). Feeds mainly on larger zooplankton like mysids, crab larvae and polychaete larvae (Ref. 26966).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (20 of 100) .
