Etymology: Doryrhamphus: Greek, dory = lance + Greek, rhamphos = bill, beak (Ref. 45335).
Issue
Issue on validity of subspecies: subspecies considered as valid in FB, synonymized with the species Doryrhamphus excisus Kaup, 1856 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). Please send references, or more studies are needed.
Environment: milieu / climate zone / depth range / distribution range
Ecologie
marien rifbewoner; diepte 0 - 8 m (Ref. 112725), usually 3 - 8 m (Ref. 112725). Tropical
Western Indian Ocean: endemic to the Red Sea from the Gulf of Suez south to Massawa and Jiddah on the east coast. It was noted by Dawson (Ref. 5316) that there is a clinal increase in the number of total rings and dorsal rays for the 3 subspecies; more study is needed (Ref. 86689).
Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 4.3 cm SL mannelijk / geslacht onbekend; (Ref. 5316)
Adults occur in reefs and tide pools at depths of about 9 m. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00085 (0.00032 - 0.00224), b=3.04 (2.81 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
