When it comes to age and longevity there are a number of factors that can determine how long a blue whale is likely to live. In most ways, Pakicetus (Greek for "Pakistan whale") was indistinguishable from other small mammals of the early Eocene epoch: about 50 pounds or so, with long, dog-like legs, a long tail, and a narrow snout.

Then it closes its mouth and strains the water out through a sieve-like filter, which traps huge amounts of tiny shrimp-like creatures called krill. 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. 10 Oldest Skateboarders in the World.

These animals evolved nostrils positioned further and further back along the snout. In fact the oldest recorded blue whale was estimated to have a lifespan of 110 years! Depending on the species of whale the average gestation period (the period from conception to birth) may vary from 10 – 17 months. For some species, like the Greenland shark which may live more than 500 years, scientists are forced to use carbon dating, but the inaccuracy of the process means that estimates can be out by more than 100 years. 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.
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.

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. This lifespan estimation is 10–20 years higher than most estimates of Lonesome George’s age at death.”. 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 researchers also determined that the natural life-span of early modern humans is only 38 years. This species of whale is known as Llanocetus denticrenatus.It’s the second oldest baleen whale ancestor ever discovered and is a distant relative to modern humpback and blue whales.
Size estimates vary, but the American Cetacean Society says blue whales can grow about 100 feet (30 meters) long and weigh more than 100 tons (91,000 kilograms). Dr Benjamin Mayne, the author of the study said that vertebrates can have very varying lifespans, from a tropical fish called pygmy goby that lives for only 8 weeks to Bowhead whales that can live for 268 years. “It is rarely possible to follow long-lived species from birth to death as they would normally out live a generation of researchers. Despite their massive size and relatively long lifespan these whales consume a relatively simple diet consisting primarily of krill, a small aquatic life form that measures 1 – 2 centimeters on average with a maximum size of around 6 inches. The blue whale can be bigger because it feeds in a much different and highly efficient way, the study says. Disclosure Policy | Privacy Policy | Copyright © 2020 WhaleFacts.org. The blue whale is believed to mature between 8 – 10 years of age. Leave a comment Cancel reply. 10 Oldest Street Railway Systems in the World. 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 team also applied their lifespan clock to extinct species and discovered that the life expectancy of Neanderthals was 37.8. 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… The research was published in the journal Scientific Reports. Reaching lengths of between 70 – 90 ft on average the blue whale is the largest living animal in the world. Reaching lengths of between 70 – 90 ft on average the blue whale is the largest living animal in the world. Some bowhead whales have been discovered with harpoons dating from the 1880s, proving they can survive for huge periods but their true lifespan has remained a mystery. Human shouting is 70 decibels; sounds over 120 decibels are painful to human ears.
