Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had been listed in "Guinness World Records" as the world's oldest living pony, died in 2007 at age 56.
Long-tailed goral
The goral's average lifespan in the wild is 10–15 years, although a captive goral was aged at 17 years." The females will go into a 30- to 40-hour estrus cycle once per year, when they can be fertilized by a male. At the end of a 215-day gestation period, they give birth to one offspring, or very rarely twins." Breeding within the zoo systems has been successful, with the San Diego Zoo especially so.
