Etymology: Gouania: From Antoine Gouan, in Montpellier was the author of a "Historia piscium" (Ref. 45335); pigra: Name from Latin adjective masculine singular nominative 'piger' in Lepadogaster piger Nardo 1827, meaning slow-moving. It was changed to 'pigra' in Gouania pigra which is an adjective feminine singular nominative, following the necessity of agreement in gender (Article 31.2, ICZN, 1999)..

Short description
Identification keys | Morphology | Morphometrics
Vertebrae: 39 - 40. This species is distinguished from its congeners by the following characters: dorsal head profile in lateral view 'S' curved, concave above the eye and convex at the nape; posterior angle of jaws extends to, or close to, vertical line drawn through anterior edge of anterior nostril; infraorbital invagination below anterior half of eye or below mideye; posterior opercular edge with 2 tips, the upper longer or equal to lower; longitudinal infralateral and suborbital transversal rows of superficial neuromasts located in the well-defined deep groove; body cross-section behind pectoral fin base half oval to pentagonal with a straight ventral side; body granules shallow and inconspicuous; pectoral rays 13-16; upper attachment of disc membrane attached to base of pectoral fin at 12th-15th pectoral ray; principal caudal rays 10-11; head length 19.5-22.9% of SL: pectoral-fin length 5.6-7.5% of SL; prepectoral distance 19.5-23.4% of SL; ventral adhesive disc length, 12.1-14.6% of SL; caudal-fin length 11.1-12.7% of SL; large total number of vertebrae 39-40; pharyngeal jaws with elongated ceratobranchial 5, with several larger elongated conical teeth; nasal bones hook-shaped; star-like pigmentation around eyes absent, pigmentation generally reduced (Ref. 123696).
Inhabits intertidal pebble beaches, where it might be found even above the waterline during low tide, and rarely occurs in fields of larger boulders (Ref. 123696).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00202 - 0.01305), b=3.11 (2.89 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.5 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.).
Fishing Vulnerability (Ref.
