Grizzly Bear 'Super Mom' Gives Birth To Her 17th Cub Despite Her Old Age

A grizzly bear super mum famous for showing tourists her cubs at the roadside has given birth to her 17th baby despite being one of the oldest grizzlies to live outside a zoo. In the wild grizzly bear sows don't live long past 26 years, but 24-year-old Bear 399 who inhabits the Grand Teton National Park, Wyoming has just produced a new litter. Remarkably she has had four cubs, which itself is extremely rare as bears on average only have two or three.
