Etymology: Ctenogobiops: Greek, kteis, ktenos = comb + Latin, gobius = gudgeon + Greek, ops = appearance (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 20 m (Ref. 48637), usually 1 - 5 m (Ref. 90102). Tropical; 30°N - 23°S
Indo-West Pacific: Red Sea to New Caledonia, north to the Ryukyu Islands; Truk and Guam in Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm SL male/unsexed; (Ref. 48637)
soft rays: 10 - 11. Characterized by whitish body color with three longitudinal rows of large brown spots; dark blotch behind eye; head with small dark spots/streaks; white spots on basal portion of pectoral fin; longitudinal scale series 54-57; opening of gill extending to vertical at posterior edge of preopercle; greatest depth of body 4.7-5.5 in SL; rounded caudal fin, about equal to head length (Ref. 90102).
Occurs in sand and rubble bottoms of shallow lagoons (Ref. 9710) and subtidal reef flats. Often with Ctenogobiops pomastictus. Usually in pairs and use the burrow of alpheid prawns for refuge. Lives in clear coastal and inner reefs on rubble flats and slopes in 6 to 20 meters depth range (Ref. 48637). Feeds on small benthic invertebrates (Ref. 89972).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.2 - 29.3, mean 28.3 °C (based on 2585 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00271 - 0.01339), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
