Morphology

Morphometrics
Distinguished from congeners in Iceland by the following characters: presence of parr marks in adults; flank dark brown with irregular golden or yellow spots, belly beige to yellowish, usually blackish markings on throat (not much difference between breeding and non-breeding coloration); pectoral fins black, other fins beige, caudal and dorsal fins with pale spots; snout blunt, rounded, about equal to eye diameter; mouth subinferior, upper jaw projecting (Ref.
59043
).
Inhabits shallow littoral zone, with water 0-10 m deep. A nocturnal species which hides between stones during the day. Feeds predominantly on snails, and to a lesser extend on benthic insects (Ref.
59043
).

Estimates based on models
Phylogenetic diversity index (Ref.

): PD
50
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00468 - 0.02039), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

).
Trophic level (Ref.
69278
): 3.7 ±0.5 se; based on size and trophs of closest relatives
Generation time: 6.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
