Question

Which animal holds the record for the longest lifespan?

Answer 1

The animal with the longest lifespan is the bowhead whale, which can live for up to 211 years.

Bowhead whales are one of the longest living mammals in the world. They are found in the Arctic and sub-Arctic waters, and can grow up to 20 meters in length. They feed mainly on plankton and small fish, and are known for their distinctive white heads and long, curved jaws.

Answer 2

The longest-living animal is the ocean quahog, a type of clam, which can live up to 500 years. The oldest known individual was discovered in Iceland and was estimated to be 507 years old. These clams have a slow metabolism and grow very slowly, allowing them to live such long lives.

Answer 3

The animal with the record of the longest lifespan is the Green land shark it has an average lifespan span of three hundred years to four hundred years 

Answer 4

Greenland shark 

The longest living vertebrate known to science is a five-metre-long Greenland shark, collected dead in 2016 and estimated to be 392 years old, with a margin of error of 120 years.

Answer 5

The animal that holds the record for the longest lifespan is the ocean quahog (Arctica islandica), a type of clam found in the North Atlantic Ocean. These clams are known to live for more than 500 years, with the oldest known specimen living for 507 years. The exact reasons for their long lifespan are not yet fully understood, but it is believed to be related to their slow metabolism, low levels of predation, and ability to repair DNA damage over time. Other animals with exceptionally long lifespans include the Greenland shark, bowhead whale, and giant tortoise.

Answer 6

The animal that holds the record for the longest lifespan is the ocean quahog, scientifically known as Arctica islandica. These marine bivalve mollusks have an incredibly long lifespan. Some individuals have been documented to live for more than 500 years, making them one of the longest-lived animals on Earth. Their remarkable longevity is due to their extremely slow growth rate and low metabolic activity, which results in a gradual accumulation of growth rings on their shells, similar to tree rings. This makes them a subject of scientific interest for understanding longevity and environmental changes over extended periods.

Answer 7

The Greenland shark holds the record for the longest lifespan among animals, with individuals documented to live for over 400 years, making them some of the longest-living vertebrates on Earth.
