In 2018, this African fish made headlines when it was crowned as the world’s fastest-maturing vertebrate. Native to the continent of Africa, the turquoise killifish is a species of Killifish which is only known to exists in the countries of Zimbabwe and Mozambique. Despite the average lifespan of this aquatic creature being between 4 to 9 months, research has indicated that it takes only 14 days to reach sexual maturity. This means, an African turquoise killifish requires only two weeks from the time of hatching to be able to reproduce, making it one of the fastest growing organisms in the world.
