The mating time of whales is very short, with a gestation period of 11 and a half months, which is more than those born in winter. For each birth, the length of the newborn whale is about 5 meters. The lactation period is 6-7 months and the life span is about 50 years.

Second, the loneliest whale in the world is Alice, who was discovered in 1989 and has been recorded since 1992. In the eyes of other whales, Alice looks like a mute. She has no relatives or friends for so many years, no one hears her when she sings, and no one pays attention to her when she is sad. The reason is that the frequency of this lonely whale is 52 hertz, while the frequency of a normal whale is only 15-25 hertz, her frequency has always been different.
