Etymology: Paracheilinus: Greek, para = the side of + Greek, chaite = hair + Greek, odous = teeth (Ref. 45335).
Eponymy: Dr John Edward McCosker (d: 1945) is an ichthyologist and evolutionary biologist who is Senior Scientist and first Professor of Aquatic Research at California Academy of Sciences, San Francisco. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 5 - 50 m (Ref. 90102), usually 5 - 40 m (Ref. 27115). Tropical; 25°C - 28°C (Ref. 27115)
Indo-West Pacific: western Indian Ocean to Fiji. Questionable record from Indonesia (Ref. 8631).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 11441)
Only the first dorsal soft ray prolonged in adults; penultimate dorsal soft ray of males 1.6-2.0 in HL; a single short dark stripe beneath pectoral fin (Ref. 41634).
Inhabits outer reef slopes, over rubble, algae, or coral (Ref. 9710). Occurs in small groups of mix sexes but females outnumber males greatly (Ref. 48636). Swim close to the bottom and females swim in small groups. Males swim around them and often hurry from one area to another where there are groups of females. Some juveniles are secretive and often single or small groups amongst the rubble (Ref. 48636).

Estimates based on models
Preferred temperature (Ref.
123201): 26.2 - 29.1, mean 28.2 °C (based on 1868 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 138 [79, 283] mg/100g; Iron = 1.06 [0.60, 2.06] mg/100g; Protein = 18.1 [15.2, 20.3] %; Omega3 = 0.178 [0.099, 0.313] g/100g; Selenium = 24.9 [13.0, 50.2] μg/100g; VitaminA = 242 [72, 905] μg/100g; Zinc = 2.04 [1.31, 3.24] mg/100g (wet weight);
