what animal has an average life span of 50 years?

Macaws 30 to 50 years– the smaller mini-macaw at the lower range.\n\nCockatoos 30 to 40 years.\n\nAmazons 50 years or more with proper care. The average is more like 20 years due to the fact that amazons are prone to obesity and fatty liver disease which can lead to death.

The average lifespan for a wolf in the wild is only 9 years. Wolves in captivity live much longer. They reach sexual maturity at about 2 years of age and have finished growing.

There are several kinds but, I believe, only three that inhabit humans.  They can reach a length of 50 ft and can live 20-30 years depending on the specific species.

An orthodontist's nightmare, a beaver's front teeth never stop growing\n\nBeavers in the wild live about 10 to 12 years. They have been known to live as long as 19 years in captivity. They continue to grow throughout their lives and may reach 3 to 4 feet (0.9-1.2 m) long, including tail. Although most adult beavers weigh 40 to 70 pounds (17-32 kg), very old, fat beavers can weigh as much as 100 pounds (45 kg).\n\nThey can reach speeds of up to 6 m.p.h. when swimming.\n\nAmerican Indians called the beaver the "sacred center" of the land because this species creates rich habitats for other mammals, fish, turtles, frogs, birds and ducks. \n\nBeavers mate for life during their third year.\n\nWildlife rehabilitators find beavers to be gentle, reasoning beings who enjoy playing practical jokes.

The oldest horse that ever lived was "Old Billy". He was born in Lancashire in 1760 and lived to the world record age for horses of 62 years!\n\nThe average life span of a horse is only 20. And that is actually quite old. 20horse years, would be like a human living to 100.\n\n-D

It depends on the kind of turtle it is. Some can live for a hundred years.

1.)No one knows for sure how long killer whales live. \n\n2.) For unknown reasons, killer whales have a high calf mortality rate in some areas of the world.  In the Pacific Northwest, for example, 43% of all calves die in the first six months.  In other killer whale populations, calf mortality may be as high as 50% during the first year. \n\n3.)  Long-term studies will ultimately answer this question.  By counting growth layers in teeth, scientists find that killer whales in the North Atlantic may live at least 35 years.  Studies are still refining this method of aging. \n\n\nResearchers can estimate a killer whale's age by examining a sliced section of tooth and counting growth layer groups.\n\n\n4.)  Scientists in the Pacific Northwest estimate life expectancies by using information derived from field observations that began in the 1970s.  These scientists believe that if a killer whale survives the first six months, a female's life expectancy is 50 years and a male's is 30 years. \n\n5.)  With continued research, it is likely that differences in longevity will be found in killer whale populations around the world.

Apparently upto 4 years, depending on species. See \n\nhttp://www.seahorses.de/seahorses.htm\n\nAnother site,\n\nhttp://seahorse.fisheries.ubc.ca/biology4.html\n\nhas this to say\n\nNatural lifespans for seahorses are virtually unknown. Most estimates come from laboratory or aquarium observations. Known lifespans for seahorse species range from about one year in the smaller species to an average of three to five years for the larger species.

Penguins....they live longer & can be petted

The average life span for males is 30,000 days which is about 84 years it you are lucky you live to be older.  but the average age for males is  20.4 years old

I would say so.\n\nIt's been shown as well that seniors who have pets live longer. Whether it's the social aspect or having the responsibility of caring for them, I don't know.

Although they may live up to two years in the lab, the average mouse in the wild lives only about 3 months, primarily due to heavy predation. Cats, wild dogs, foxes, birds-of-prey, snakes and even certain kinds of insects have been known to prey heavily upon mice.\n\nYou could get more information from the link below...

yes.....having an animal as a pet is good for the heart, relaxes it more and most that have pets in their lives actually live a longer life.

Theres no set age for it. The average lifespan is supposedly 31-36 but hes already beat that so need to drag him down. Hes a lucky man. Tell him goodluck lol not that he needs it though :)
