Question

A penguin life span is how long?

Answer 1

An emperor penguin life span is 20 years. And
A little penguin life span is 6 years.

Answer 2

The lifespan of a penguin variesdepending upon the species. Magellanic penguins can live up to 30 years – the longest lifespan of any penguin around the world – while little blue penguins have the shortest lifespan of up to six years.
However, there are other factors that can influence the length of time that a penguin lives. Penguins, like all animals, are known to live much longer in captivity as they are removed from their natural predators and have access to a reliable source of food. Penguin chicks are also more likely to survive into adulthood as a result of the protection from external threats that captivity provides.
