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).
Body shape (shape guide): elongated.

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).

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