Etymology: Helcogramma: Greek, helkos, -eos, -ous = ulcer, sore + Greek, gramma = letter, mark (Ref. 45335)lacuna: The specific epithet is from the Latin lacuna meaning cavity, cavern, or hollow. The name refers to holes in the rocky reefs inhabited by all members of the fuscopinna complex and is treated as Noun in apposition.

Biologia     Glossario (es. epibenthic)

Adults inhabit sand channels in patch reefs (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

Preferred temperature (Ref. 123201): 28.6 - 29.4, mean 29.1 °C (based on 41 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00304 - 0.03005), b=3.02 (2.77 - 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
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
