Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae
Pups are born in dense breeding colonies. Perinatal attendance averages one week, then mothers forage offshore several days at a time. Upon arrival from sea, mother and pup reunites using vocalization signals and olfactory cues, i.e., naso-nasal contact. Lactation lasts at least 12 months.
