Reproduction and life cycleo lion:
Lion Reproduction and Mating Behavior
The reproductive cycle of lionesses begins around four years of age, and they are polyestrous, meaning they can mate at any time of the year. Male lions have spines on their penis that stimulate ovulation during withdrawal. During mating, a lioness may mate with multiple males. Interestingly, both male and female lions may engage in homosexual and courtship activities, including head-rubbing and simulating sex. The generation length of lions is approximately seven years.
Lion Cubs and Parental Care
The gestation period of a lioness is around 110 days. She gives birth to a litter of one to four cubs in a secluded den, such as a thicket or cave, away from the pride. Initially, the lioness hunts alone while protecting her helpless cubs, who are born blind and weigh around 1.2 to 2.1 kg (2.6 to 4.6 lb). The cubs start crawling within a day or two and begin walking by three weeks of age. To protect the cubs from predators, the lioness frequently moves them to new den sites, carrying them one-by-one by the nape of their necks.
Usually, the lioness reintegrates herself and her cubs into the pride when the cubs are six to eight weeks old. Sometimes, if other lionesses have recently given birth, the introduction to pride life occurs earlier. Lion cubs initially lack confidence but gradually immerse themselves in pride activities, playing among themselves and attempting to interact with adult lions. Lionesses with cubs are generally more tolerant of other lionesses' cubs, while male tolerance varies from individual to individual.

Communal Rearing and Suckling
Pride lionesses often synchronize their reproductive cycles, leading to communal rearing and suckling of the young. Cubs suckle from any nursing female in the pride, ensuring equal access to nourishment and minimizing dominance by older cubs. Weaning typically occurs after six or seven months.
Maturity, Dispersal, and New Male Takeovers
Male lions reach sexual maturity at around three years of age, and between four to five years, they become capable of challenging and displacing adult males associated with other prides. Male lions begin to weaken and show signs of aging at 10 to 15 years of age. When new males take over a pride, they often kill any existing young cubs. This behavior may be driven by the fact that females do not become fertile until their cubs mature or die. While lionesses fiercely defend their cubs, they are rarely successful unless multiple lionesses unite against the intruding male. Cubs also face threats from starvation, abandonment, and predation by leopards, hyenas, and wild dogs.
Male cubs are typically forced to leave their maternal pride when they reach maturity at around two to three years of age, while some females may leave at two years of age. The eviction of adolescents occurs when a new male lion takes over a pride.
