Balaenoptera edeni brydei Olsen, 1913

Taxonomic Identification Challenges

Several anatomical differences exist between Bryde's whales (Balaenoptera edeni brydei Olsen, 1913) and Eden's whales, but morphological similarities between the two have led to confusion in species identification.

Breeding Frequency

For reproduction and nurturing, Bryde's whales breed every other year.

Breeding Seasonality

Breeding can occur in any season, though it reaches a peak in autumn.

Gestation Period

The gestation period of Bryde's whales is estimated to be 12 months.

Newborn Calf Characteristics

At birth, calves measure 3.4–4.0 m (11–13 ft) in length and weigh 1,000 kg (2,200 lb).

Sexual Maturity

Bryde's whales reach sexual maturity at 8–13 years of age, when females are 12 m (39 ft) long.

Nursing Period

Mothers nurse their calves for 6–12 months.
