Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες

Only sexually mature Steller sea lions return to rookeries, except for few dependent young with their mothers. Gestation results only one pup which is nursed for under a year up to 3 years. Mothers stay on shore with their newborn for about a week before leaving for regular feeding trips. Copulation usually occur prior to first feeding trip. Longevity lasts about 14 years for males and 22 years for females, with a generation time of 10 years.
