Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2 - 3; Dorsal soft rays (total): 18 - 20; Anal spines: 1; Anal soft rays: 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).

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).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

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. 115969): 6.8 - 14.3, mean 9.8 (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).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1; tmax=1; Fec=340).

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