[ 131 ] The oldest living spider , named Number 16 by researchers, was a 43-year-old female Gaius villosus armored trapdoor spider , at the North Bungulla ...
The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, and can reach lengths from 3 to 13 ft (0.91 to 3.96 m) depending on the locality and the availability of suitable prey.

Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals ...
They reach sexual maturity after 10 to 15 years. In captivity their life span is around 54 years. In the wild their lifespan is unknown but is believed to exceed 75 years. [10] [6] The tortoise has no known predators when they are hatchlings or adults. [6] In fact it is believed that they are nearly immune to predators when their weight exceeds ...
Adult gopher snakes average between 36-84 in ... Life expectancy. Wild gopher snakes typically live 12 to 15 years, but the oldest captive recorded lived over 33 ...
Life expectancy in the wild is thought to be over 100 years, [110] [111] making it one of the longest-lived species in the animal kingdom. Harriet , a specimen kept in Australia Zoo , was the oldest known Galápagos tortoise, having reached an estimated age of more than 170 years before her death in 2006. [ 112 ]
However, the species' life expectancy in the wild is only 1.8 to 3.1 years, depending on the local conditions such as traffic volume, hunting, and weather severity. [203] It is not unusual for only half of the young born in one year to survive a full year. [186] [204] After this point, the annual mortality rate drops to between 10% and 30%. [186]
Red-eared slider turtles are the world's most commonly traded reptile, due to their relatively low price, and usually low food price, small size, and easy maintenance.
