However, young people play a lot alongside their father. Silverback gorilla in Gaia Zoo ( Angela Meder) What do a silverback's penis and testicles look like In relation to their body mass, the testicles and penis of a gorilla are not very noticeable and much smaller than in other apes.

An average silverback gorilla can weigh up to 180kg (that’s almost 30 stone), and measure 170cm (over 5’5) tall on all fours. Their reproductive rate is low, the female gives birth to one baby gorilla per year, especially since twins are rare and the gestation period is about 9 months. They’re one of the biggest, most powerful living primates. The life expectancy of the western gorilla in nature is around 45 years. When the males start to have a more developed silver back they also leave their group of origin, become solitary and start looking for other family groups to convince females to join them and form a new group. The silverback gorillas strength is exceptional. Gorillas in captivity have grown to be much larger, weighing up to 683.433 lb (310 kg). When it was shot in Cameroon, the worlds heaviest gorilla in the wild weighed 588.634 lb (267 kg). Male gorillas weigh much more than female gorillas weigh. Females leave their native group at the time of their sexual maturity to join other silverbacks to reproduce. A male gorilla typically weighs 440 lb (181.437 kg). The social structure of the western gorilla is made up of a silverback, adult females generally between 3 and 7 and their offspring. Unlike eastern gorillas, only one silverback male is tolerated and present per group. composed of 12 members, had 1 silverback male, 5 adult females.

Gorillas are the worlds largest primates, with males weighing around 143-169kg and standing about 1.4-1.8m tall in the wild. During the dry season, the nests are simply constructed but can become more elaborate depending on the degree of rain and consist of cool branches that isolates the moisture from the soil. In the evenings, they build their nests mainly on the ground next to the dominant male. The western gorilla groups are very cohesive, all members remain at a distance allowing auditory contact with the dominant male. The female reaches half of the male size and reproduces for the first time between 8 years and 11 years, much earlier than for the male. ![]() The male completely develops the silver color of his back around the age of 18. ![]() The western gorilla is physically smaller than the eastern gorilla.
