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.

Depends on which part of the life cycle and which species.  For example, some species have a laval life span of several years, and an adult (breeding stage) life span of weeks to months...

There are alsmost certainly more red kangaroos alive today than prior to European settlement of Australia. While many other species of smaller wallaby have become rare or extinct because of predation by foxes and cats and changes in the environment because off grazing and fire, red kangaroos have largely benefited by the establishment of permenant water supplies in what has historically been a country prone to droughts, and the improvemnent of pastures for cattle. Australians would be far better off eating Kangaroos than cattle, they are much better for the environnment, have less fat, cook more quickly and require much less water per kilogram.

Depends how fast someone steps on it.\nMost araneomorph spiders (orb weavers, huntsman, etc.) live from one to three years. Mygalomorph spiders (trapdoors, tarantulas) are generally much longer lived. Some large tarantulas species (Theraphosidae) take six to eight years to mature and live 20 years or more. A long life and continuing moulting and growth allows some of these species to grow very large - the legs of a large goliath spider (Theraphosa blondi) may almost span a dinner plate. \n\nFemale spiders generally live longer than males, this difference being especially notable in long-lived spiders like mygalomorph spiders - e.g., male funnelwebs mature in two to three years and then die about nine months later; whereas females mature in three to four years but may live for many years (six or more) after that\n\n\nHere is more info on the spider and a very interesting site about spiders.  Take a look at it you'll love it.\n\nSpiders are ancient animals with a history going back many millions of years. They have always been with us, an ancient source of fear and fascination. They are abundant and widespread and are natural controllers of insect populations. Wherever you live, you're always close to a spider. \n\n\nSpiders grow by periodically shedding their semi-rigid external 'skin' or cuticle of semi-rigid chitin and replacing it with a new larger skin they have grown underneath the old one (this is called ecdysis or moulting). This process includes replacement of every hair on the body and internal cuticular structures such as the fore and hind gut linings and female genitalia. Once they are mature most araneomorph spiders stop moulting. However, female mygalomorph spiders moult throughout life, although at longer intervals as they get older. This allows some species, particularly tarantulas (Theraphosidae), to grow very large. \n\nDuring the moulting process, which may take many hours, the spider is in great danger from predators, being soft-bodied and unable to move until its new cuticle has hardened. For this reason moulting is often done at night hanging safely in mid-air from a silk line; or sealed within a silk retreat or moulting chamber, e.g., in a curled leaf, a burrow, or under bark. \nSpider eggs develop and hatch within the egg sac, the larval spider undergoing at least one further moult before emerging from the sac. The number of growth moults varies between species, as well as with size and nutritional state. Poorly fed spiders will moult fewer times and become smaller adults. Most spiders undergo 5-10 moults to reach adulthood. Males often have fewer and faster moults. Extreme examples of this are given by the Magnificent spider (Ordgarius magnificus) and the Bird Dung spider (Calaenia kinbergi), both large, specialised moth catching relatives of the orb weavers. The males moult only within the egg sac, emerging as tiny, fully mature males along with their similarly sized and very immature sisters, which will take many weeks and moults to become large adult females. \n\nA spider's appearance can change considerably during growth from spiderling to adult, as indicated by these stages in Redback Spider development. Adult males and females also may look quite different, especially in respect of size and colour. Spiders with good eyesight like jumping spiders often have colourful or strikingly marked males which differ considerably from their drabber females.

Depends on if its an adult tick or a freshly hatched tick.... if adult how much blood has it sucked on its last feeding? If an average sized tick it could survive for about 1 to 2 weeks... but usually they will find a way out of the house before that time is up, they are so small they can get outside w/o windows and doors being opened....

In the wild, many male tarantulas have been shown to have an average life expectancy of only about five years, while females often live 25 to 30 years.\n\nThe survivorship of captive specimens may be much higher, where they have adequate food, water, and shelter, stable environments, no predators, and possibly most important, no chance for females to eat them during mating season.

Im an auzzie, and Ive never heard the phrase, but I will tell you, if you want to feed a kangaroo, particularly a big red fella, prepare to get the thrashing of your life. They are not cute as they are depicted, little ones are mild mannered, but ALL have long razor claws on front and back feet, and massive muscles designed to kick each other with. The red ones can be 8ft tall or more, so yeah, auzzies know, you dont feed kangaroos...we usually shoot em and eat em!

I dont think they live too long, I found an article that say the life cycle is about 14 days and as little as 4 days.

It depends on the species. Large apple snails can live over 10 years. Small pond, ramshorn, trumpet, etc. snails may live 3-6 years but most die before that when they are eaten or due to poor water quality or something else. Trapdoor snails may live 5-10 years. The average run-of-the-mill small aquarium snail is lucky to live a few years with all the predators and dangers in the average tank. But, really there is no definitive answer to your question. I don't know that anyone's done real studies on this. It's just word of mouth as to how long someone's snail may have lived.

no.  the more complex an organism, the easier they go extinct.\n\ntrilobites lasted around 300 million years; a not-so-complex animal.\n\ndinosaurs lasted about 150 million years; more complex, shorter reign.\n\nhumans, we haven't even come CLOSE to how long dinosaurs we around, we'll go extinct soon enough.

Good question. Many animals live longer in captivity because once they have adapted to their human-made conditions (and some are born there), they have no predators, no intraspecific competition and usually a team of vets taking care of them. \nIt's not easy to find reliable records of lifespan for wild dolphins, due to their life habits. A wild dolphin lived 20 years  and a bottle-nosed dolphin lived 35 years (see link for references); some people indicate that their average lifespan is 46-48 years but they don't cite sources or species.  Captive animals usually have shorter lifespans, and wild-captured individuals are sometimes  very stressed and die; again, not many reliable sources out there (which would be understandable if aquariums did not want comparisons to be made from the data). There's a 30-year record for a captive bottlenose dolphin; many webpages state shorter lifespans, but again, no statistics or reliable sources.\nI'd like to read the opinions of knowledgeable Answerers out there!

This depends upon the species of kangaroo.  The small rat-kangaroo, which can weigh less than half a kilogram (1 lb.), to red kangaroos, which can weigh more than 80 kilograms (175 lbs.).

About one week depending on the species.

a pig lifespan is about 15

Most kangaroos are exclusively plant-eaters, with grasses forming the bulk of their diet. They also feed on moisture-filled succulent plants. Only the musky rat kangaroo eats insects and worms as well.\n\nKangaroos can go without water for long periods. Some wallaroos do not drink water even when the temperature is very high. They conserve body water by hiding in hollows during the hottest part of the day.

The Grammostola cala, or Rose Hair Tarantula, one of the most popular pet "spiders", have a life span of about 5 years. They are 3 - 4 inches standard leg span and native to the country of Chile.
