Etymology: Crystallogobius: Latin, cristallum = ice + Latin, gobius = gudgeon (Ref. 45335).
Milieu: milieu / Klimaatzone / Diepte / verspreidingsgebied
Ecologie
marien demersaal; standvastig (Ref. 4696); diepte 1 - 400 m (Ref. 35388). Temperate; 70°N - 35°N, 11°W - 25°E
Eastern Atlantic: Lofotens, Norway, to Gibraltar. Also known from the Mediterranean Sea. Eastern Central Atlantic: Madeira Island (Ref. 74541).
Lengte bij maturiteit / Grootte / Gewicht / Leeftijd
Maturiteit: Lm 2.7, range 3 - 3.3 cm
Max length : 4.7 cm SL mannelijk / geslacht onbekend; (Ref. 4696); 3.9 cm SL (female); max. gerapporteerde leeftijd: 1.00 Jaren (Ref. 232)
Dorsale stekels (totaal) : 2 - 3; Dorsale zachte stralen (totaal) : 18 - 20; Anale stekels: 1; Anale zachte stralen: 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 the eggs found in empty tubes of sedentary polychaetes such as Chaetopterussp. and Protula sp. (Ref. 49498). Semelparous, adults die after breeding (Ref. 4696).
