figure out which animals are longest - lived is slippery , because some punt the organisation . Immortal jellyfish , for example , clone themselves in their puerile polyp stage , a phase to which they can return later in life story . It ’s a jaw - dropping feat — but is it the samejellyfishor a newborn copy ?
suspend animation is another loophole . According to a recent field inCurrent Biology , scientists thawed microscopic rotifers — which had been in a state of cryptobiosis in Siberian permafrost for24,000 years — that started asexually multiply like it was their cockcrow routine .
take such outlier into consideration , here are the animals that will probably get the mostfree natal day scoopsfromBaskin - Robbinsin their super - foresightful lifetimes .

1. Deep Sea Sponges // 2300-18,000 years
A species of mysterious sea glass poriferan ( Monorhaphis chuni)produces an extremely longspicule , or pinched structure , made of silica , with the leech part on the top . It looks a bit like an artsy floor lamp . Much like tree rings , the bed of silica record climate fluctuations as well as the geezerhood of the animal . A 2017 study of sea make-up over metre that includedM. chunispicules estimated they were between5000 and 18,000 years honest-to-god .
In 2008 , another study reckon at the growth rate of the giant barrelful quick study ( Xestospongia muta ) figure they can live more than2300 years .
2. Greenland Shark // 400-500 years
Though they ’re slowly - moving and usually blinded by eye parasites , Greenland shark ( Somniosus nanocephaly ) are still one of the top piranha in the Arctic and the world ’s longest - lived craniate . A 2016studyon a 16 - foot Greenland shark , which was caught in fishing nets as by-catch , used anew techniqueto date the animal . By radiocarbon - dating a protein inside their eyes , which forms before nascence and remain viable throughout their lives , scientists estimated the specimen was about 392 year honest-to-god , give or take 120 class . That suggests the shark can live between 272 and 512 years .

They may die by getting eaten , fished , or a specific disease , but veryrarely(if at all ) from sometime eld .
7. Aldabra Giant Tortoise // 189 years and counting
If this lean notice the most famous long - lived animate being , Aldabra giant tortoises ( Aldabrachelys gigantea ) would sure enough be on top .
