Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 2 - 3; Mjukstrålar i ryggfenan (totalt) : 18 - 20; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 20 - 21. Patterns of sensory papillae require detailed description. Pronounced sexual dimorphism. Anterior nostril a short tube. Pectoral fin uppermost rays within membrane. Males: with prominent front canine teeth; pelvic disc complete and deep; 1st dorsal with only 2 with rays. Females: pelvic disc reduced or lacking; 1st dorsal absent or rudimentary. Vertebrae 30(29-31).
Body shape (shape guide): elongated.

Benthic and free swimming (Ref. 92840). This occasionally territorial species occurs in coastal waters, over shell, sand, or mud bottoms; males bottom-living during breeding season. Feed on zooplankton (Ref. 5204). Spawning takes place when 1 year old. Adults die afterwards. Eggs are laid in the empty tube-worms and are guarded by the male (Ref. 35388). Eggs are pear-shaped (Ref. 4696).

Males guard eggs in empty tubes of larger worms, such as Chaetopterus. Adults die after breeding (Ref. 4696).

Estimates based on models

Preferred temperature (Ref. 123201): 6.8 - 14.3, mean 9.8 °C (based on 546 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (tm=1; tmax=1; Fec=340).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100). 🛈
