Etymology: Pholis: Greek, pholis, -idos = scale (Ref. 45335).
More on author: Cope.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 73 m (Ref. 50610). Temperate
Eastern Pacific: Bering Sea coast of Alaska and the Aleutian Islands to Crescent City, northern California, USA. Early records might be misleading since Pholis laeta was once considered identical to Pholis ornatus and was recorded as Pholis ornatus (Ref. 4925).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 2850)
Morphology | Morphometrics
Facultative air-breathing in the genus (Ref. 126274); Frequently in intertidal areas, in tide pools or under rocks protected by seaweeds (Ref. 2850). May remain out of water under rocks or seaweed (Ref. 31184). Probably feeds on small crustaceans and marine worms (Ref. 28499). Breathes air when out of water (Ref. 31184).
Life cycle and mating behavior

Phylogenetic diversity index (Ref. 82804
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00162 (0.00068 - 0.00388), b=3.19 (2.99 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.39 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 (15 of 100).
