how long is the gestation period for humpback whales
Humpback whale Females typically breed every two or three years. The gestation period is 11.5 months. The peak months for birth are January, February (northern hemisphere), July and August (southern hemisphere). Females wait for one to two years before breeding again. Recent research on mitochondrial DNA reveals that groups living in proximity to each other may represent distinct breeding pools.[28] Humpback whale births have been rarely observed. One birth witnessed off Madagascar occurred within four minutes.[29]
Gestation In humans, birth normally occurs at a gestational age of about 40 weeks, though it is common for births to occur from 37 to 42 weeks.[1] After 8 weeks, the embryo is called a fetus.
