Descrição suscinta Morfologia | Morfometria

Espinhos dorsais (total): 3; Raios dorsais (total): 6-8; Espinhos anais 3; Raios anais : 5; Vértebras: 40 - 42. Caudal fin with 15-16 rays (Ref. 2196). Single small spot on upper caudal base. Pigmentation (Gambetta's longitudinal zone of pigmentation): zones Z1-Z4 usually well differentiated, extending backward to caudal peduncle; height of blotches of zone Z4 usually less than 2 times in their length; if more than 2 times, then height equal to or greater than horizontal eye diameter. One lamina circularis (Ref. 59043).

Biologia     Glossário (p.ex. epibenthic)

Adults occur in slow-flowing and still waters with fine sandy substrate (Ref. 9696). They occur in the Baltic Sea at salinities of up to 5 ppt (Ref. 59043). Filter sand for food particles (Ref. 36876). Nocturnal, stays hidden under rocks or buried in the sand or mud during the day (Ref. 30578). Oviparous, with distinct pairing during breeding (Ref. 205). Spawn in spring; scatters eggs into mats of plant material (Ref. 36876). Eggs are found attached to gravel and weed in shallow, flowing water (Ref. 41678). Larvae hide under vegetation and in debris until beginning of exogenous feeding (Ref. 59043).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Start of courtship is observed when both male and female swim excitedly then progresses to a chase done by the male. When movements become synchronised, the male entwines itself around the female's body, squeezing it and causing egg spawning (Ref. 58425). Triploid females can occur; they produce triploid eggs which can develop without fertilization, but need contact with sperm to start development (gynogenesis) (Ref. 36876). Also Ref. 9953.
