Scientists from the Institute of Vertebrate Biology in the Academy of Sciences in the Czech Republic have discovered the fastest maturing vertebrate species in the world.

Scientists from the Institute of Vertebrate Biology in the Academy of Sciences in the Czech Republic have discovered the fastest maturing vertebrate species in the world.
A species of small Killifish that live in temporary puddles in the savanna of southern Mozambique, Africa reach sexual maturity in only 17 days.

The same species also has the shortest minimum generation time of all the vertebrate animals, and in just over a month these fish go from being an egg to having their own offspring.

Dr Martin Reichard who worked on the study said: “I'm pretty sure if conditions are good, they would be able to sexually mature even faster in the wild.”

They also have the shortest life span of any vertebrate ever studied in captivity at a maximum of 11 weeks, with a significant increase in deaths around 6 weeks.

When the puddles they live in dry up, the embryos and eggs are left dormant in the sand and are able to survive for several months until the next rainfall fills up the same puddle again.
