What is human fish life?

Here, we show that the ‘human fish’ (olm, Proteus anguinus), a small cave salamander (weighing 15–20 g), has evolved an extreme life-history strategy with a predicted maximum lifespan of over 100 years, an adult average lifespan of 68.5 years, an age at sexual maturity of 15.6 years and lays, on average, 35 eggs every

How many Olms are left in the world?

Scientists believe that the cave salamander lives as long as it does because of the cool water of its environment and its slow metabolism. How many Olms are left? There are at least 400 olms left in the world. Its conservation status is vulnerable.
