Sir Smoke aLot Posted December 14, 2017 #2 Share Posted December 14, 2017 From Instagram post : '' it also requires that there is no annoying animal eating the tag before we get the data which happened to us on a previous deployment. '' 3 Link to comment Share on other sites More sharing options...
_KB_ Posted December 14, 2017 #3 Share Posted December 14, 2017 well technically all animals can live about 8 cycles under ideal circumstances so humans could be living 350 years, it's just highly unlikely that a creature would never get sick or hurt too badly and maintained a healthy life style, bound to happen every so often no?

paperdyer Posted December 14, 2017 #4 Share Posted December 14, 2017 She didn't look too aggressive considering a person was near. Maybe she's just gotten to the point that chasing us isn't worth it. Now if we go in the water, all bets are off, or isn't this shark a carnivore? Link to comment Share on other sites More sharing options...

Greenland sharks are slow movers and eat we presume is carcasses. Please don' assume all sharks are many eaters 2 Link to comment Share on other sites More sharing options...

Please don' assume all sharks are many eaters I'm not as I know they aren't. As with snakes, as I'm not 100% sure of what all the poisonous ones look like, I treat them all as poisonous and steer clear.

No cases of Greenland shark predation on humans have ever been recorded. 1 Link to comment Share on other sites More sharing options...

The Greenland shark has the longest known lifespan of all vertebrate species.[20] One Greenland shark was tagged off Greenland in 1936 and recaptured in 1952. Its measurements suggest that Greenland sharks grow at a rate of 0.5–1 cm (0.2–0.4 in) per year.[21] In 2016, a study based on 28 specimens that ranged from 81 to 502 cm (2.7–16.5 ft) in length determined by radiocarbon dating of crystals within the lens of their eyes, that the oldest of the animals that they sampled, which also was the largest, had lived for 392 ± 120 years. The authors further concluded that the species reaches sexual maturity at about 150 years of age.[20][ https://en.m.wikipedia.org/wiki/Greenland_shark 1 Link to comment Share on other sites More sharing options...

oldrover Posted December 19, 2017 #10 Share Posted December 19, 2017 Apparently it's only 392. Nipper. Link to comment Share on other sites More sharing options...
Aardvark-DK Posted December 20, 2017 #11 Share Posted December 20, 2017 Fascinating. Yes it has slow movement, and a slow biology. A bit like landbased turtles, which can reach a very high age. Sounds plausibly... Link to comment Share on other sites More sharing options...
