The change in metabolism, brain to body ratio, environment, and many unknown factors makes different lifespan for different species. Some animals live for hundreds of years like bowhead whales and eels. At the same time, the lifetime of some other species of animals limited to only a few hours. Here the list of 10 shortest living animals in the world.

7 Chameleon, 1 Year
Panther chameleons only have a lifespan of 1 year. In fact, it is the shortest lifespan among reptiles and chameleon family. Panther chameleons are native to Northern and Eastern parts of Madagascar. They show rapid mating behavior because of shorter life span. Interestingly the entire adult chameleons disappeared before next generation emerges out from the eggs. The rapid color changing is the most noticeable characteristic of chameleons. So that they can blend into the natural environment. The diet of chameleons mainly includes crickets and worms.
6 House Mouse, 1 years
The average lifespan of house mouse is 1 year. But predators like cats and poisoning will shorten the life span of these small mammals even shorter. House mouses are also prone to many health problems during hair growing stage. They are also prolific breeders because of shorter life span.
5 Dragon Fly, 4 months
There are 5000 different species of dragonflies are in the world. The maximum lifespan of the beautiful insect is about 4 months. But most of the dragonflies won’t live that much time because they can be easily eaten by spiders, birds, lizards and frogs.

2 Gastrotrichs, 3 Days
Gastrotrichs are one of the marine microorganisms that are used to live in marine environments. They grow up to a maximum size of 3 millimeters and have life circle of 3 days. They have transparent body structure and swim along with currents. They also used to attach with other water bodies using hundreds of adhesive tubes on the lower part of the bodies.
