Zoological Research Confirms Fin Whale Gestation Lasts Approximately 11 Months

Fin whale pregnancies last close to 11 months, resulting in calves already several meters long at birth.

Fin whale calves can gain up to 90 kilograms per day while nursing.

Reproductive studies compiled by NOAA and peer-reviewed marine mammal journals indicate fin whale gestation spans roughly 11 months. Calves are typically born measuring about 6 to 6.5 meters in length. Lactation may continue for six to seven months following birth. Reproductive intervals often extend two to three years between calves. Such spacing limits rapid population recovery. Pregnancy timing aligns with migration to lower-latitude waters. Maternal energy investment is substantial given calf size. Growth accelerates quickly during nursing. Reproduction defines recovery ceiling.

Understanding gestation and calving intervals shapes population growth models. Government conservation plans rely on reproductive rate assumptions. Institutions evaluating endangered status consider intrinsic growth potential. Slow reproductive cycles limit rebound after overexploitation. Demographic modeling integrates calf survival rates and adult mortality. Biology constrains recovery speed. Protection must account for generational pacing.

For the public, the image of a six-meter newborn recalibrates expectations. Even infancy arrives at large scale. Maternal investment in giants begins long before birth. The ocean hosts pregnancies measured in tons. Recovery depends on each calf reaching maturity. Time stretches across decades. Patience defines conservation.
