In order to power their massive bodies these gigantic animals can consume as many as 8,000 pounds (4 tons) of krill or 40 million krill per day. They reached out with a long pole to attach sensors to the creatures with suction cups, allowing them to record what the animals were doing on their dives for food.

The Bowhead whale was previously known to have an average life span of 211 years, but Australian researchers have used a genetic 'clock' to predict that these animals can live nearly 60 years longer than what was previously known. The researchers also determined that the natural life-span of early modern humans is only 38 years. Reaching lengths of between 70 – 90 ft on average the blue whale is the largest living animal in the world. Depending on the species of whale the average gestation period (the period from conception to birth) may vary from 10 – 17 months.

That’s the conclusion of researchers who used small boats to chase down 300 whales of various species around the world. Dr Mayne added that this new technique can help save these animals from extinction, this method can only be used to determine the lifespan of species and not of individuals.

As stated earlier the blue whale is a marine mammal and is part of the cetacean family, which also includes dolphins and porpoises. “Using our lifespan estimator and the bowhead whale genome, we estimated the maximum longevity of the bowhead whale to be 268 years. Now, a groundbreaking genetic study has built the first ‘lifespan clock’ which can predict how long an animal will live, simply based on its DNA. The study also included the biggest whale with teeth, the sperm whale, which can stretch about 60 feet (18 meters) long, the group says. The 'lifespan clock' screens 42 selected genes for short pieces of DNA whose density is correlated with lifespan, to predict how long members of a given vertebrate species may live. However, the researchers found it was impossible to create a clock for invertebrate species from their DNA, and they have not yet tested it on the Greenland shark, so its true age continues to remain elusive. Even more surprising is the fact that during migration periods these whales go into a fasting state and can live for up to 4 months without consuming any (or very little) food while they make their long 3,000 mile migration trip from the Atlantic to warmer tropical environments by living off of the fat and blubber they’ve stored around their bodies.

The blue whale can be bigger because it feeds in a much different and highly efficient way, the study says. These animals evolved nostrils positioned further and further back along the snout. “It kicks off the bowhead whale as the oldest vertebrate animal,” said Julius Nielsen, lead author of the research from the University of Copenhagen, pointing out … Some of these factors include being hunted by humans (and rare killer whale attacks), food supply shortages and the health of their food, climate changes, water and noise pollution, mental and physical health (sickness and injuries can significantly reduce the health and longevity of these majestic creatures) and a host of other age affecting factors.

Surviving for at least 200 years, the bowhead whale is the longest living mammal on Earth but zoologists have struggled to discover its true life expectancy. Researchers use amino acids in the eyes of whales to determine the age of the whales. This lifespan estimate is 57 years more than the oldest aged individual to date.”. “The lifespan clock also creates a new opportunity to study the biology of extinct species, where ancient DNA methods can provide genome assemblies,” added Dr Mayne. A Greenland shark has lived at least 272 years, making the species the longest-lived vertebrate in the world – smashing the previous record held by a 211-year-old bowhead whale… Based on these numbers, the researchers estimated the age of each sampled whale and compared those estimates to the whales’ known ages. The method also only provides averages. ... 10 Oldest Rainforests in the World. Gallery: 55 mesmerizing photos of whales (Photo Services). As stated earlier the blue whale is also the largest living creature in the world with the biggest blue whales growing to incredible lengths that are in excess of 100 feet and weigh over 150 tons when fully matured.
