Can Cockroaches Really Survive the Apocalypse? A List of the Longest-Living Insects
Apr 26, · But that doesn’t stop the following from being crowned the longest living insects: Cicadas: 17 years Cicadas are the bugs you can hear making a racket during the summer. The phrase longest-living insect is a little ambiguous. Does it refer to the average life-span of an insect or the amount of time a particular species of insect has existed? We .
We humans like to pride ourselves on our long and getting longer all the time life spans, but the surprising fact is that, in terms of longevity, Homo sapiens have nothing on other members of the animal kingdom, including sharks, whales, and even salamanders and clams.
In this article, discover the 11 longest-lived largesy of various animal families, in order of increasing life expectancy. One normally thinks of insects as living only a few days, or at most a few weeks, but if you're a particularly important bug all the rules go out the window. Whatever the species, a colony of termites is ruled by a king and queen; after being inseminated by the male, the queen slowly ramps up her production of eggs, starting with a mere couple of dozen and eventually attaining levels of close to 25, per day of course, not all of these eggs ineect, or else we'd all be knee-deep in termites!
Unmolested by predators, termite queens have been known to reach 50 years of age, and the kings who spend pretty much their entire lives holed up in the nuptial chamber with their prolific mates are comparably long-lived.
In the wild, fish rarely live for more than a few years and even a well-cared-for goldfish will be lucky to reach the decade mark. But few lsrgest in the world are more tenderly indulged how to draw lego friends koi, a variety of the domestic carp that populates the "koi ponds" popular in Japan and other parts of the world, including the U.
Like their carp cousins, koi can withstand a wide variety of environmental conditions, though especially considering their bright colors, which are constantly being tinkered with by humans they're not especially well-equipped to defend themselves against predators.
Some koi individuals have been reputed to live for over years, but the most widely accepted estimate among scientists is 50 years, which is still a lot longer than your average fish-tank denizen. In many ways, macaws are unnervingly similar to suburban Americans of the s: these colorful how to install arcgis 10 desktop crack relatives mate for life; the females incubate the eggs and care for the young while the males forage for food; and they have human-like life spans, surviving for up to 60 years inxect the wild and years in captivity.
Ironically, even though macaws have unusually long life spans, many species are endangered, a combination of their desirability as pets and the devastation of their rainforest habitats. If you were asked to identify liviny animal that regularly hits the century mark, the blind salamander, Proteus anguinuswould probably be close to last on your list: how can a fragile, eyeless, cave-dwelling, six-inch-long amphibian possibly survive in the wild for o be careful little eyes what you see sheet music than a couple of weeks?
Naturalists attribute P. What's more, the dank caves of southern Europe where this salamander lives are virtually devoid of predators, allowing P. For the record, the next longest-lived amphibian, the Japanese giant salamander, only rarely passes the half-century mark.
Human beings so regularly hit the century mark—there are aboutyear-olds in the world at any given time—that it's easy to lose sight of what an astonishing advance this represents. Tens of thousands of years ago, a lucky Homo sapiens would have been described as "elderly" if she lived into her twenties or thirties, and until the 18th century or so, average life expectancy rarely exceeded 50 years.
The main culprits were high infant mortality and susceptibility to fatal diseases; the fact is that at any stage of human history, if you somehow managed to survive your early childhood and teens, your odds of making it to 50, 60 or even 70 were much brighter. To what can we attribute this stunning increase in longevity? Well, in a word, civilization—especially sanitation, medicine, nutrition, and cooperation during the Ice Agea human tribe might have left its elderly to starve in the cold; today, we make special efforts to care for our octogenarians and nonagenarians.
As a general rule, larger mammals tend to have comparably longer life spans, but even by this standard, the bowhead whale is an outlier: adults of this hundred-ton cetacean regularly exceed the year mark.
Recently, an analysis of the Balaena mysticetus genome shed some light on this mystery: it turns out that the bowhead whale possesses unique genes snl digital short mmm whatcha say aid in DNA repair and resistance to mutations and therefore cancer.
Since B. Today, there are about 25, bowhead whales wyat in the northern hemisphere, a healthy rebound in population sincewhen serious international efforts were made to deter whalers.
The giant tortoises of the Galapagos Islands and the Seychelles are classic examples of "insular gigantism"—the tendency of animals confined to island habitats, unmolested by predators, to grow to unusually large sizes. And these turtles have lifespans that perfectly match their to 1,pound weights: giant tortoises in captivity have been known to live longer than years, and there's every reason to believe that testudines in the wild regularly hit the year mark.
As with some of the other animals on this list, the reasons for the giant tortoise's longevity are self-evident: these reptiles move extremely slowly, their basal metabolisms are set at an extremely low level, and their life stages tend to be comparably stretched out for example, the Aldabra giant tortoise takes 30 years to attain sexual maturity, about double the time of a human being.
If there were any justice in the world, the Greenland shark Squalus microcephalus would be every bit as well-known as the great white: it's just as big some adults exceed 2, pounds and much more exotic, given its northern Arctic habitat. You can lviing make the case that the Greenland shark is just as dangerous iw the star of Jawsbut in a different way: whereas a hungry great white shark will bite you in half, the flesh of S.
What to do in nyc summer 2013 that said, though, the most notable thing about the Greenland shark is its year lifespan, which can be attributed to its sub-freezing environment, its relatively low metabolism, and the protection afforded thf the methylated compounds in its muscles.
Astonishingly, this largesst doesn't even reach sexual maturity until it's well past the year mark, a stage when most other vertebrates are not only sexually inactive but long since dead.
A year-old mollusk sounds like the setup for a joke: given that most clams are virtually immobile, how can you tell if the one you're holding is living or dead? There are, however, scientists who investigate this kind of what is a msc degree stand for for a living, and they have determined that the ocean quahog, Arctica islandicacan literally survive for centuries, as demonstrated by insec individual that passed the year mark you can determine the age of a mollusk by counting the growth rings in its shell.
Ironically, the ocean quahog is also a popular food in some parts of the world, meaning that most individuals never get to celebrate their quincentennials. Biologists have yet to figure out why A. Determining the lifespan of a microscopic organism is a tricky matter: in a sense, all bacteria are immortal, since they propagate their genetic information by constantly dividing rather than, like most higher animals, having sex and dropping dead.
The term "endoliths" refers to bacteria, fungi, amoebas or algae that live deep underground in the clefts of rocks. Studies have shown that the individuals of some of these colonies only undergo cell division once every hundred years, endowing them with lifespans in the 10,year range. Technically, this is different from the ability of some microorganisms to revive from stasis or deep-freeze after tens of thousands of years; in a meaningful sense, these endoliths are continuously "alive," albeit not very active.
Perhaps most importantly, endoliths are autotrophic, meaning that they fuel their metabolism not with oxygen or sunlight, but with inorganic chemicals, which are virtually inexhaustible in their underground habitats.
There's no really good way to determine how old your average jellyfish is; these invertebrates are so fragile that they don't lend themselves well to intensive analysis in laboratories. However, no livinng of the longest-lived animals would be complete without a mention of Turritopsis dohrniia jellyfish that has the ability to revert back to its juvenile polyp stage after reaching sexual maturity, thus id it potentially immortal.
However, it's pretty much inconceivable that any T. Ironically, too, it's nearly impossible insectt cultivate T. Share Flipboard Email. Bob Strauss. Science Writer. Cite this Article Format. Strauss, Bob. The 11 Longest-Lived Animals.
Queen Termites: Decades, under the right conditions
Jul 26, · The world's largest insect is two feet long, lives only in isolated pockets of Malaysia, was discovered just three years ago and remains a mystery to biologists. The Heaviest Insect: A Goliath Beetle from tropical Africa, weights in at 3 1/2 ounces. The Heaviest Water Insect: The Giant Water Bug of South America, tips the scales at nearly two ounces. The Longest-jumping Insect: One species of fleas jumps times their own body length. Oct 24, · The current record holder for the largest insect that ever lived is an ancient griffenfly. Meganeuropsis permiana measured an impressive 71 cm from wing tip to wing tip, a full inch wing span. This giant invertebrate predator inhabited what is now the central U.S. during the Permian period.
The largest organisms now found on Earth can be determined according to various aspects of an organism's size, such as: mass, volume, area, length, height, or even genome size.
Some organisms group together to form a superorganism such as ants or bees , but such are not classed as single large organisms. The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2, km 1, mi , but contains many organisms of many types of species. This article lists the largest species for various types of organisms and mostly considers extant species. The organism sizes listed are frequently considered "outsized" and are not in the normal size range for the respective group.
If considered singular entities, the largest organisms are clonal colonies which can spread over large areas. Pando , a clonal colony of the quaking aspen tree , is widely considered to be the largest such organism by mass.
At 8 kilometres 5 mi across, and estimated at around , years old,  it may be one of the largest and oldest clonal colonies on Earth. Among animals , the largest species are all marine mammals , specifically whales. The blue whale is believed to be the largest animal to have ever lived. The largest land animal classification is also dominated by mammals , with the African bush elephant being the largest of these.
The largest single-stem tree by wood volume and mass is the giant sequoia Sequoiadendron giganteum , native to Sierra Nevada and California; it typically grows to a height of 70—85 m — ft and 5—7 m 16—23 ft in diameter. The largest organism in the world, according to mass, is the aspen tree whose colonies of clones can grow up to 8 kilometres 5 mi long. Another form of flowering plant that rivals Pando as the largest organism on earth in breadth, if not mass, is the giant marine plant, Posidonia oceanica , discovered in the Mediterranean near the Balearic Islands , Spain.
Its length is about 8 km 5 mi. It may also be the oldest living organism in the world, with an estimated age of , years. Green algae are photosynthetic unicellular and multicellular protists that are related to land plants. The thallus of the unicellular mermaid's wineglass, Acetabularia , can grow to several inches perhaps 0. The fronds of the similarly unicellular, and invasive Caulerpa taxifolia can grow up to a foot 0.
A member of the infraorder Cetacea , the blue whale Balaenoptera musculus , is thought to be the largest animal ever to have lived. The maximum recorded weight was tonnes for a specimen measuring The African bush elephant Loxodonta africana , of the order Proboscidea , is the largest living land animal.
A native of various open habitats in sub-Saharan Africa, this elephant is commonly born weighing about kilograms lb. It was a male measuring This male had a computed weight of The heaviest living animals are all cetaceans , and thus also the largest living mammals. Since no scale can accommodate the whole body of a large whale, most whales have been weighed by parts. The following is a list of the heaviest wild land animals, which are all mammals. The African elephant is now listed as two species, the African bush elephant and the African forest elephant , as they are now generally considered to be two separate species.
The largest tunicates are Synoicum pulmonaria , found at depths of 20 and 40 metres 66 and ft , and are up to 14 centimetres 6 in in diameter. It is also present in the northwestern Atlantic Ocean, around the coasts of Greenland and Newfoundland, but is less common here than in the east, and occurs only at depths between 10 and 13 metres 33 and 43 ft.
The largest thaliacean , Pyrosoma atlanticum , is cylindrical and can grow up to 60 cm 2 ft long and 4—6 cm wide. The constituent zooids form a rigid tube, which may be pale pink, yellowish, or bluish. One end of the tube is narrower and is closed, while the other is open and has a strong diaphragm. The outer surface or test is gelatinised and dimpled with backward-pointing, blunt processes.
The individual zooids are up to 8. Along the side of the branchial sac runs the endostyle , which produces mucus filters. Water is moved through the gill slits into the centre of the cylinder by cilia pulsating rhythmically. Plankton and other food particles are caught in mucus filters in the processes as the colony is propelled through the water.
The largest lancelets: European lancelet Branchiostoma lanceolatum "primitive fish". It can grow up to 6 cm 2. The blue whale is the largest mammal. The largest land mammal extant today is the African bush elephant. The largest extinct land mammal known was long considered to be Paraceratherium orgosensis , a rhinoceros relative thought to have stood up to 4.
The Triassic period Lisowicia bojani , from what is now the southern Poland, probably was the largest of all non-mammalian synapsids most of which became extinct million years ago , at 4. Anteosaurus was 5—6 m 16—20 ft long, and weighed about — kg 1,—1, lb. The largest living reptile , a representative of the order Crocodilia , is the saltwater crocodile Crocodylus porosus of Southern Asia and Australia, with adult males being typically 3.
The largest confirmed saltwater crocodile on record was 6. A specimen named Lolong caught alive in the Philippines in died February was found to have measured 6. A member of the monitor lizard family Varanidae , it is the largest living species of lizard, growing to a maximum length of 3 metres 9.
The following is a list of the heaviest living reptile species ranked by average weight, which is dominated by the crocodilians. Unlike mammals, birds, or fish, the mass of large reptiles is frequently poorly documented and many are subject to conjecture and estimation.
The largest living bird , a member of the Struthioniformes , is the common ostrich Struthio camelus , from the plains of Africa and Arabia. A large male ostrich can reach a height of 2. The largest bird in the fossil record may be the extinct elephant birds Aepyornithidae of Madagascar, which were related to the kiwis.
Aepyornis exceeded 3 m 9. Of almost exactly the same upper proportions as the largest elephant birds was Dromornis stirtoni of Australia , part of a 26,year-old group called mihirungs of the family Dromornithidae. The tallest bird ever was the giant moa Dinornis maximus , part of the moa family of New Zealand that went extinct around AD. This particular species of moa stood up to 3.
The heaviest bird ever capable of flight was Argentavis magnificens , the largest member of the now extinct family Teratornithidae , found in Miocene-aged fossil beds of Argentina, with a wingspan up to 5. The following is a list of the heaviest living bird species based on maximum reported or reliable mass, but average weight is also given for comparison.
These species are almost all flightless, which allows for these particular birds to have denser bones and heavier bodies. The largest living amphibian is the South China giant salamander Andrias sligoi.
Formerly considered conspecific with the Chinese giant salamander A. The largest known was the crocodile -like Prionosuchus , which reached a length of 9 m 30 ft. The largest known species of sea sponge is the giant barrel sponge, Xestospongia muta. These massively built sponges can reach 2. The lion's mane jellyfish Cyanea capillata is the largest cnidarian species, of the class Scyphozoa.
The largest known specimen of this giant, found washed up on the shore of Massachusetts Bay in ,   had a bell diameter of 2. The tentacles of this specimens were as long as 37 m ft and were projected to have a tentacular spread of about 75 m ft making it one of the longest extant animals. The largest roundworm , Placentonema gigantissima ,  is a parasite found in the placentas of sperm whales which can reach up to 9 m 30 ft in length.
The largest of the segmented worms including earthworms, leeches, and polychaetes is the African giant earthworm Microchaetus rappi. Although it averages about 1. The largest species of echinoderm in terms of bulk is probably the starfish species Thromidia gigas , of the class Asteroidea , which reaches a weight of over 6 kg 13 lb ,  but it might be beaten by some giant sea cucumbers such as Thelenota anax.
However, at a maximum span of 63 cm 25 in , Thromidia gigas is quite a bit shorter than some other echinoderms. In comparison, the biggest sea star is the brisingid sea star Midgardia xandaros , reaching a span of 1. The largest nemertean is the bootlace worm , Lineus longissimus. A specimen found washed ashore on a beach in St. Andrews , Scotland in was recorded at a length of 55 m ft. Both the largest mollusks and the largest of all invertebrates in terms of mass are the largest squids.
The colossal squid Mesonychoteuthis hamiltoni is projected to be the largest invertebrate. In , authorities in New Zealand announced the capture of the largest known colossal squid specimen. It was initially thought to be 10 m 33 ft and kg lb. It was later measured at The giant squid Architeuthis dux was previously thought to be the largest squid, and while it is less massive and has a smaller mantle than the colossal squid, it may exceed the colossal squid in overall length including tentacles.
One giant squid specimen that washed ashore in in Newfoundland reportedly measured 18 m 59 ft in total length from the tip of the mantle to the end of the long tentacles , head and body length 6. This specimen is still often cited as the largest invertebrate that has ever been examined. An adult female was recorded to have a body length of 22 cm approximately 8. The largest arthropod known to have existed is the eurypterid sea scorpion Jaekelopterus , reaching up to 2.
Its legs may span 1 m 3. The largest crustaceans are crab Tasmanian giant crab '' Pseudocarcinus gigas 13 kilograms 29 lb and a carapace width of up to 46 centimetres 18 in. It is the only species in the genus Pseudocarcinus. The females' shells change colour when they are producing eggs. At a length of up to 40 centimetres 16 in , Lysiosquillina maculata is the largest mantis shrimp in the world. The four modern horseshoe crabs are of roughly the same sizes, with females measuring up to 60 cm 2.
The largest of the sea spiders is the deep-sea species Colossendeis colossea , attaining a leg span of nearly 60 cm 2. Some of these extinct marine arthropods exceeded 60 cm 24 in in length.
A nearly complete specimen of Isotelus rex from Manitoba attained a length over 70 cm 28 in , and an Ogyginus forteyi from Portugal was almost as long. Fragments of trilobites suggest even larger record sizes.
