They live long lives On average blue whales live 80 to 90 years. The oldest blue whale ever found was around 110 year old. Scientists can estimate the age of a deceased whale by counting the bands of light and dark wax in its ears, like counting tree rings.
Whale Lifespan Some whales have a lifespan similar to humans, particularly the blue and the fin whales as they reach up to 85 years old. The life cycle of a whale varies from type to type, but the best known species have the following.
Blue whales are the largest baleen whale species--in fact they are the largest animal in the world. Blue whales can grow to be about 100 feet (30.5 meters) in length and may weigh around 160 tons. They are mottled bluish gray, with broad flat heads and a small dorsal fin located in the last forth of the body.
The average lifespan of a blue whale is estimated at Fact Sheet A blue whale's blowhole is like a huge pair of nostrils, which can reach up to 50 centimetres (20 inches) in length. The spray from a blue whale's blowhole can shoot as high as 9 metres (30 feet) into the air.
Blue whale, (Balaenoptera musculus), also called sulfur-bottom whale, the most massive animal ever to have lived, a species of baleen whale that weighs approximately 150 tons and may attain a length of more than 30 metres (98 feet). The largest accurately measured blue whale was a 29.5-metre female that weighed 180 metric tons (nearly 200 short (U.S.) tons), but there are reports of 33-metre.
Manx Shearwater — Average Life Span is 15 Years But There Are Impressive Exceptions While their average life span is only about 15 years, there's one Manx shearwater whose been circling the globe for at least 51 years and who has flown an estimated 5 million miles in his lifetime.
The killer whale, or orca (Orcinus orca), is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin.
Blue whales are among Earth's longest-lived animals. Scientists have discovered that by counting the layers of a deceased whale's waxlike earplugs, they can get a close estimate of the animal's.
