Etymology: Enneapterygius: Greek, ennea = nine times + Greek, pterygion = little fin (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 23 m (Ref. 27223). Tropical
Pacific Ocean: Hawaiian Islands, French Frigate Shoals, Laysan Island, and Midway Atoll.
Length at first maturity / Size / Weight / Age
Maturity: Lm 1.5  range ? - ? cm
Max length : 2.6 cm SL male/unsexed; (Ref. 27223)
Adults are benthic in dead coral, rubble, or rock (Ref. 58302). 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. 115969
): 24.2 - 26.4, mean 25.3 °C (based on 59 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00244 - 0.01183), 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
Generation time: 0.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
