this is a 396 years old Greenland shark these sharks can live up to 400 years when Greenland sharks gets old they often go blind due to a parasite that latches onto their eye the Greenland shark prefers to hunt in dark the loss of eyes doesn't affect their ability to hunt these sharks have a unique sexual maturity a remarkable Revelation has captured the attention of scientists world wide growing to lengths of up to 7 m and weighing as much as 1,000 kg this shark was born in 1627 some of these elusive Giants have been roaming the oceans long before the birth of Isaac Newton the groundbreaking discovery of the 396 year old Greenland shark was made possible through the use of radiocarbon dating a technique that analyzes the levels of carbon 14 in the shark's eye lenses unlike other tissues such as muscle or cartilage eye lenses are metabolically inert providing a pristine record of an organism's carbon intake over its lifetime by analyzing the carbon levels in the ey lenses of Greenland sharks scientists can estimate the age of these remarkable creatures with unprecedented accuracy the revelation of a 396 year old Greenland shark shattered previous records for vertebrate longevity cementing its status as one of the oldest known vertebrates on Earth what makes the Greenland shark's longevity even more remarkable is its slow growth rate and reproductive maturity these sharks grow at a sluggish Pace with females not reaching sexual maturity until they are around 156 years old an age that far surpasses is the total lifespan of other shark species It is believed that they grow at a rate of only a few ctime per year which contributes to their prolonged lifespan Greenland Sharks play a crucial role in maintaining the delicate balance of Arctic ecosystems as apex predators they help regulate populations of prey species ensuring the health and stability of marine food webs however there slow reproductive rate make them particularly vulnerable to human activities like overfishing and habitat destruction.
