New research into the life spans of great white sharks shows that these predators can live as long as humans - at least into their 70s. Sharks are considered endangered. Logged in Doomwatch Legacy by Sunstroke author David Kagan.

With so many Assians in the planet they won't live long.

Sure they can but do they get the chance to live that long? With people killing them for one reason or another what are the chances they will be able to live to a ripe old age?

Only if they can manage to avoid humans for their whole lives.

I didn't know they lived that long. If people would stop killing them, then we'd know how long they lived.

So true Natasha.

Whale lifespans vary among species and are not well characterized. Whaling left few older individuals to observe directly. R.M. Nowak of Johns Hopkins University estimated that humpback whales may live as long as 77 years. In 2007, a 19th century lance fragment was found in a bowhead whale off Alaska, suggesting the individual could be between 115 and 130 years old. Aspartic acid racemization in the whale eye, combined with a harpoon fragment, indicated an age of 211 years for another male, which, if true would make bowheads the longest-lived extant mammal species.
