The average lifespan of gorillas in the wild and in captivity can vary depending on factors such as species, gender, environmental conditions, and overall health. Here are the average lifespans of the different gorilla species:
1. Western Gorilla (Gorilla gorilla):
- Western Lowland Gorillas: In the wild, Western lowland gorillas have an average lifespan of about 35 to 40 years. In captivity, they can live into their 40s or 50s, with some individuals reaching their 60s.
- Cross River Gorillas: Information on the lifespan of Cross River gorillas is limited, but it is expected to be similar to that of Western lowland gorillas.
2. Eastern Gorilla (Gorilla beringei):
- Mountain Gorillas: Mountain gorillas have a longer lifespan compared to Western lowland gorillas. In the wild, they can live for about 40 to 50 years. In captivity, they may live into their 50s or even 60s.
- Eastern Lowland Gorillas (Grauer's Gorillas): Information on the lifespan of Eastern lowland gorillas is limited, but it is believed to be similar to that of Mountain gorillas.
It's important to note that these are general estimates, and individual gorillas can live longer or shorter lives depending on various factors. In the wild, gorillas face threats such as poaching, habitat loss, and diseases, which can affect their lifespan. In captivity, where they receive appropriate care, nutrition, and veterinary attention, gorillas may have longer lifespans compared to their wild counterparts.
