Short description 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).

Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00286 - 0.01390), b=3.08 (2.90 - 3.26), 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. 69278):  High, minimum population doubling time less than 15 months (tm=1; tmax=1; Fec=340).
Prior r = 1.08, 2 SD range = 0.42 - 2.78, log(r) = 0.08, SD log(r) = 0.47, Based on: 1 K, 1 tgen, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
