deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)) : 16 - 17; duri punggung lunak (Keseluruhan (total)) : 11 - 13; Duri dubur: 1; Sirip dubur lunak: 19 - 21; vertebrata, bertulang belakang: 36 - 38. A species of Helcogramma (sensu Hansen, 1986) with 1-2 symphysial mandibular sensory pores, second dorsal fin spines XIII (two of 26 specimens with XIV), third dorsal fin segmented rays 10-12, last ribs on vertebral centrum 11, vertebrae modally 11+26=37 (value range: 11+25 to 27=36 to 38), pored lateral line scales modally 25 (value range: 23-29), nape scales absent, males with dorsal, caudal and anal fins dark.

Adults inhabit exposed rocky and coralline boulders of coasts (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 25.5 - 29.4, mean 28.4 °C (based on 964 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
