white sturgeon are prehistoric-looking fish that can reach a length of 8 m and a mass of 850 kg. white sturgeon are called living fossils because they have not changed much during their 175 million years on earth. having survived volcanic eruptions, ice ages, and the extinction of dinosaurs, white sturgeon are now threatened because of human alteration of their environment. for example, the nechako white sturgeon population has dropped from over 5000 fish to fewer than 600 in the past 50 years. most of these fish are more than 30 years old, but in the past, sturgeon as old as 160 years have been found. the lack of younger fish means that either white sturgeon are not reproducing successfully or the young are not surviving to adulthood.
