Kurzbeschreibung Morphologie | Morphometrie

A species of Helcogramma (sensu Hansen, 1986) with 14 symphisial mandibular sensory pore, second dorsal fin spines XIV-XV (one of 11 specimens with XIII), third dorsal fin segmented rays 11-12, last ribs on vertebral centrum 12, vertebrae modally 10+28=38 (value range: 10+27 to 29=37 to 39), pored lateral line scales modally 22 or 23 (value range: 22-25), nape scales present, male with thirs dorsal, caudal and anal fins dark and posterior half of body dark.

Adults are found in rocky boulders of exposed 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).

Estimates based on models

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): 3.1 ±0.3 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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