Which mammal lives the longest?

The mammal that lives the longest is the bowhead whale. Bowhead whales are a type of cetacean, a group of marine mammals that includes whales, dolphins, and porpoises. Bowhead whales are native to the Arctic and sub-Arctic waters of the North Atlantic and North Pacific Oceans. They are large, slow-moving animals that can grow to be up to 60 feet long and can weigh up to 100 tons. Bowhead whales have a lifespan of around 200 years, making them the longest-lived mammals on earth. Other long-lived mammals include certain species of bats, elephants, and some species of whales and dolphins.

What about the lifespan of different mammal species?

It is difficult to provide a complete list of the lifespan of all mammal species, as there are more than 5,000 species of mammals and their lifespans can vary significantly. However, here is a list of some examples of the lifespan of some common mammal species:

  1. Humans: 70-90 years (although some individuals may live longer)
  2. Dogs: 10-15 years (varies by breed and size)
  3. Cats: 12-15 years (varies by breed and size)
  4. Elephants: 60-70 years
  5. Bats: 5-30 years (varies by species)
  6. Whales and dolphins: 30-100 years (varies by species)
  7. Lions: 10-14 years
  8. Bears: 20-30 years (varies by species)
  9. Giraffes: 15-20 years
  10. Hedgehogs: 4-7 years

It is important to note that these are just a few examples, and the lifespan of any particular mammal can depend on a variety of factors, including diet, habitat, and genetics.
