Etymology: Cirripectes: Latin, cirrus = curl fringe + Greek, pektos, -e, -on = made of several parts solidly united (Ref. 45335);  obscurus: Specific epithet 'obscurus' meaning dark, refers to the dark coloration of the fish.

Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 15-17; Anal spines: 2; Anal soft rays: 16 - 17; Vertebrae: 31 - 33. Diagnosis: Dorsal fin XII, 16, membrane attached to caudal fin, with deep notch above last spine, first spine almost same or slightly higher than second; anal fin II, 17; pectoral rays 15; pelvic fin I, 4; caudal fin procurrent rays 10-14. Vertebrae 10 + 22. LL, without scales but with scalelike flaps irregularly spaced along anterior part of LL; LL tubes 0-10 (usually 0-8), canal ends on caudal fin base. Lower lip crenulated mesially but plicate laterally. Upper lip crenulae 41-50. Gill rakers 26-30. Cephalic sensory pore complex. Cirri, supraorbital 10-26, nasal 14-42; nuchal 36-47, grouped into 2 that sometimes overlap at midpoint on nape, without nuchal flaps. Head spotted; behind each eye are pupil-sized dark spots; iris yellowish in females, orange in males; ventral surface reddish brown in males, golden brown in females. Body brown with spots, male with spots not reaching to caudal fin base, female spots white becoming lavender posteriorly up to caudal fin base (Ref. 529).

Eastern Central Pacific: native to the Hawaiian Islands (Ref. 3921) and Midway Islands (Ref. 28618).

Biology     Glossary (e.g. epibenthic)

Occur in the surge zone of rocky and coral reefs less than 6 m deep (Ref. 529, 9710, 58302). Benthic (Ref. 58302). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing (Ref. 205). Urogenital orifice of male genital papilla located at distal tip of a slender filament on a fleshy swelling behind anus; elongated testes with length equal to 2 to 3 times its width (Ref. 529).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00452 - 0.02316), b=3.02 (2.83 - 3.21), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
