How Many Times Has Baby Shark Been Viewed

Animals living under natural weather rarely approach their maximum possible age considering of very high death rates due to infant mortality, diseases, predators, bad conditions, habitat destruction, or competition for food and shelter.

Here we list 10 animals that would have the longest lifespans living under ideal circumstances.

10. Macaw

Recognisable past their brightly covered feathers, macaws are members of the parrot family. They have a long lifespan and, in the correct environment, will live to be 60 to 80 years old. There are at abode in the rainforests and feed on a mix of basics and seeds. Unfortunately, though, the bulk of these cute birds are endangered in the wild and a few are already extinct due to habitat degradation and the illegal pet merchandise.

9. African Elephant

African elephants are the largest living land animals and, with an boilerplate lifespan of seventy years, one of the oldest. Experts are able to tell the age using several characteristics including their size and number of teeth. It'south a process that requires observational skills and a lot of practice!

Females achieve breeding age around 10-12 years former and, different us, they may remain fertile for the rest of their lives. They may give birth to around 7 babies in total. Being a mummy elephant is no easy task though. Their pregnancy lasts 22 months, which is almost three times equally long every bit a human pregnancy! Read more than about elephants.

eight. Longfin Eel

Longfin eels typically live up to lx years onetime though the longest living on record reached 106! They are native to New Zealand and Australia and spend most of their life hiding in freshwater streams earlier migrating to the Pacific Ocean to breed. They only do this once in the lifetime and die after spawning. They are very wearisome-growing animals, growing only ane-2cm a year, but females eventually abound to an impressive 73–156 cm in length.

seven. Galapagos Giant Tortoise

Information technology'due south non just the Galapagos Giant Tortoise size that'south worth noting; it'southward as well their age. They can alive to be well over 100, with the oldest known to be 152! The oldest is not the most famous, though. Lonesome George was the last remaining Pinta Island Tortoise on the islands and, for a while, the world'south rarest creature. He died in 2012 at around 100 years of historic period. Like many of the animals on our list, behemothic tortoises accept a deadening footstep of life, munching on grass and other vegetation, basking in the sun and resting for up to 16 hours a twenty-four hour period.

6. Red Sea Urchin

Red sea urchins are believed to be almost immortal and are known to alive for over 200 years with no signs of ageing. They are far more likely to be eaten by a predator than dice of an historic period-related status, and a 100-yr-former is just every bit good for you and able to reproduce as a young individual. Finding the age of these spiny echinoderms is possible by measuring the levels of carbon-14, a process known equally radiocarbon dating.

5. Koi Fish

The average lifespan for Japanese Koi is around 40 years though they can alive a lot longer if living in the right conditions. I item koi, named "Hanako", was the remarkable age of 226 when she died in 1977. Scientists were able to gauge her historic period past counting growth rings in her scales.

4. Bowhead Whale

Bowhead whales can live for over 200 years, which is longer than whatever other mammal. Information technology'due south not always easy to tell their historic period, though, as they spend their lives in the Arctic and sub-Arctic and can outlast the researchers that study them. Ane style to estimate age is to base it on fragments of harpoons left in the blab of captured animals – one private had harpoon fragments dating dorsum to the 1800s! Some other mode is to use Dna to estimate lifespan, with scientists suggesting bowhead whales can live to the grand old age of 268!

3. Greenland Shark

Greenland sharks live for between 300 and 500 years and are the longest-living vertebrate. They take life very slowly, moving at an average of 0.76 mph. They grow about a cm every year, and females may not reach sexual maturity until they are 100 to 150 years erstwhile – that's one long babyhood! Despite their huge size and long lifespan though, these sharks have been a mystery to scientists for years. It was just recently that they discovered a new method of estimating age that involves radiocarbon dating the lens of the middle. New tissues are added to the lens every year and it is possible to tell the age past how much carbon isotope is nowadays in the tissues.

2. Ocean Quahog

Ocean Quahogs are an edible clam with an impressive lifespan. Many will live to see their 400th altogether and the oldest i on tape was 507 years old when it was defenseless off the coast of Iceland in 2006. Scientists were able to determine the age by counting growth rings on the trounce, similar to how we historic period trees. They tin can also find out other information too. How the shells form over fourth dimension tells scientists how the oceans have changed throughout the years – they are a living creature and a picture of life in a changing world!

one. Immortal Jellyfish

Can you lot imagine being immortal? Reaching sometime age and so instead of dying, going back and starting again as a baby? To u.s.a., this is the stuff of dreams. For the immortal jellyfish, it is real life. These amazing animals offset their life as larvae, known as planula, swirling around in the sea. They then settle on the seafloor and become static polyps before transforming into swimming medusa. And so far, and so normal. Simply, if at any phase immortal jellyfish experience injury or stress from changes in their surroundings, they can go backwards to the polyp stage and start again. And they tin do this over and over if they get the take chances. Many won't though as they become dinner for other animals.
