Lebenszyklus und Paarungsverhalten
Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fruchtbarkeit | Larven
Eggs are laid in gelatinous masses guarded by one or both parents until hatching (Ref. 35432). However, more recent evidence suggests that care is provided by the female alone (Ref. 104883).
