Mom whales leave their babies after weaning period immediately.
Mom whales stay with little whales for 15 even 30 years.
Adolesent: 2-10 years old
Sexually Mature: after 10 years old
Old age
Hiding and die
Most whales can live for at least 30 to 50 years, long-lived whales can even live hundreds of years.
When they enter old age, many whales will stop breeding and raising young whales. Like humans, female whales even menopause.
An interesting and amazing phenomenon is that old whales seem to be able to predict their death, and would leave their partners and die alone, and the so-called
"whale graveyard"
appears.(Click

Mate and reproduction
Female killer whales begin to mature at around the age of 10 and reach peak fertility around 20.
To avoid inbreeding, males mate with females from other pods. Mothers usually calve a single offspring about once every five years.
In resident pods, births occur at any time of year, although winter is the most common.
Males sexually mature at the age of 15, but do not typically reproduce until age 21.
Migration and
Males will start to associate with other males of a similar age, forming juvenile and bachelor pods of their own.
But they still stick close to their pods or remain in their own areas in most of the time.
Some of the males would leave their
mother's pods or explore different waters in the end of this stage in order to improve fertility quality.
Females will begin to explore areas and encounter whales in other areas.
