7 Incredibly Short Living Animals

Gastrotrich, 3 days

Gastrotrich is a microscopic worm-like animal found in freshwater and marine areas. About 3 mm in length, the animal’s lifespan lasts just for three days. They normally tend to feed on dead and living organisms. Further, their body plan is simple with just head, brain, gut, reproductive and sensory organs. For reproduction, Gastrotrich uses a special tubular like structure to get attached to other organisms for the reproduction process. The eggs will be hatched in less than four days in perfect environmental conditions. Usually, it is considered that they are even capable of surviving in dry pools and stagnant areas apart from freshwater habitations.
