Well depending on the species and how long ago its last meal was, it can live for anywhere from a few days to possibly a month or more. Spiders arent always sucessful predators and are commonly seen going several weeks without food, plus, if a spider can get in behind there, there is a good chance that many insects can get in there too, many of the ones you dont see in your house......I wont scare you with that too....you have enough of a problem with the spider!\n\nhaha, hope this helps!

The Fossa (a cat-like carnivore native to Madagascar) has been known to live up to 20 years in captivity.  Their lifespan in the wild is probably somewhat shorter.\n\nInteresting enough, in addition to breaking up lemur parties by ripping their limbs off, Fossae have the ability to completely evert their rectum.  I don't know why you'd want to, but the Fossa can do it.

Not my area of expertise but I have heard that the human body can last a maximum of 120 years.\n\nJust like the Terminators batterys.\n\nI plan on living to 100...or more

they live for up to 48 hours on their quest for the egg.  then they will be passed or absorbed once they die.

Leeches are pretty hardy creatures and will survive quite a while if kept in cool, fairly clean water.  In a covered container kept in a refrigerator they will live for weeks or months if you change the water once a week or so.  Keep the container covered or they may crawl out of the container and die without being in water.

By and large, trees don't have absolute lifespans, as animals do. \n\nAccording to The Straight Dope, the most striking illustration of this is the bristlecone pine, Pinus aristata. A 1948 field guide noted that bristlecones reached maturity in 200-250 years, with "extreme ages of 300-375 years." Yet only 10 years later a researcher discovered a stand of bristlecones whose average age exceeded 4,000 years and in one case 4,600 years.\n\nOther examples are less dramatic but still instructive. Red maples live 80-250 years, American chestnuts 100-300, white oaks 300-600, bald cypress 600-1,200. These extremely broad ranges suggest that assigning a "life span" to trees is merely a statistical convenience rather than a reflection of an inherent limit. It would not be surprising (to me, anyway) if much older examples of these species were found.

Blue whales live about 25-30 years!

It usually lives for 1 year. Check out this site\nhttp://en.wikipedia.org/wiki/Japanese_beetle#Life_cycle_and_control

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...

Notostracans (often just called Triops, tadpole shrimp or shield shrimp) are small crustaceans in the Branchiopoda group. Triops have internal compound eyes and a flattened shield covering the head and leg-bearing segments of the body. The order contains a single family, with only two extant genera. Their external morphology has not changed since the Triassic (appearance of Triops cancriformis around 220 million years ago). Triops cancriformis may therefore be the "oldest living animal species on earth" (Kelber, 1999).\n\nTadpole shrimps usually live near the ground of astatic pools, where they move with their ventral side down. However, lack of oxygen can force them to swim upside-down with their gill-like legs close under the surface of the water. Notostraca are omnivorous; they dig around in the mud using the frontal part of their shield, looking not only for plankton but also for larger prey such as worms, chironomid larvae and even weak tadpoles. Anostracans, often associated with notostracans, can also be a considerable part of their prey (especially when weak or dying).\n\nNotostracans sometimes even cannibalize freshly moulted members of the same species. In northern and central Europe, with few exceptions, all tadpole shrimps are female, whereas sex ratios in southern and western Europe as well as in northern Africa are near unity. These "females" possess hermaphroditic glands, but instead of selfing, parthenogenesis takes place. Modified appendages of the 11th pair of limbs bear the ovisacs with the mature eggs.\n\nTriops evolved to survive in naturally temporary ponds all over the world. As inhabitants of such, there has never been any pressure for them to become long-lived creatures. These ponds usually dry up during certain times of the year when there is no rainfall. Although the adult Triops die during these droughts, the embryos remain in a state of diapause (suspended animation) until the rains return and fill up the temporary ponds once again, making it safe for them to hatch.\n\nThe maximum life spans in the lab agree with data from field observations on Triops survival. In the lab, T. longicaudatus has a maximum lifespan of about 50 days and T. cancriformis a maximum lifespan of about 90 days, with some individuals beginning to die off as soon as 2 weeks after hatching. Secondarily, some may suffer premature deaths from moulting complications or other reasons.

No, main sequence stars (like our sun) last for about 10 billion years. It has lived for about 5 billion years or so, which means the sun has another 5 billion more years to live. After those 5 billion years are over the fusion process is stopped (due to the lack of hydrogen). The star collapses on itself and makes the star even hotter. All that heat fuses the helium and the star expands into a red giant. It will last in this form for another 100 million years or so. Then the outer layers of the red giant comes of creating a planetary nebula. Then after that gas is gone all that is left is the hot core or the white dwarf. The white dwarf cools and becomes a cold dead core (Black Dwarf)

Rotting time approx 2-5 years depending on level of activity

Some Butterflies do have a very short lifespan but not 1 day, unless killed. Remember their main role in the life cycle is to breed and lay eggs. Most Butterflies can achieve mating and egg laying within a in a  10 - 14 day period and would die soon after. Males usually die a couple of days earlier than the female Other Butterflies, particularly the fruit eating ones, have a much longer adult life span of sometimes weeks and months. The Monarch Butterfly is a migratory species and the adult life span is approximately 9-10 months.

Well, naturally put, it could last up to two months when separated from the plant. Poison tends to stay in the part of the plant that is toxic whether or not it is separated from the plant. Unless it is waterlogged, a pretty long time.

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.

The head of Death is right at the top of the moth, I actually have one right now. It's still a caterpillar, buried itself under some soil. It stays and cuccoons for about 2 or 3 weeks until it's ready to fly and search for nectar and honey to eat, they're very cool:)
