The real champion of the short life is the gastrotrich, a near-microscopic creature found in aquatic environments worldwide. The flat, transparent critters live their entire lives in less than a week, reaching sexual maturity in three days, reproducing by cloning and then dying a day or two later.
What has the shortest lifespan?
Mayfly has the shortest lifespan on Earth — 24 hours or less. Greenland shark lives over 270 years.
What is the longest living bacteria?
Permian Bacteria
In late 2000, scientists reported that they had revived four unknown strains of bacteria from the Permian era, about 250 million years ago. These Permian bacteria are now considered the oldest living organisms ever discovered in the world.
Do bacteria have short life cycles?
Bacteria don’t have a fixed lifespan because they don’t grow old. When bacteria reproduce, they split into two equal halves, and neither can be regarded as the parent or the child. You could say that so long as a single one of its descendants survives, the original bacterium does too.
What only lives for 24 hours?
Most mayfly adults only live for about 24 hours. Mayflies can be found in countries all across the globe, with over 2000 different species. In fact, the hatching of some species of mayflies even draw crowds of witnesses as thousands of adult mayflies emerge from large bodies of water.

Are bacteria immortal?
Abstract. Bacteria were traditionally thought to have a symmetrical binary fission without a clear distinction between soma and germ-line, being thus considered as immortal biological entities.
Do viruses have a lifespan?
The only life process a virus undergoes independently is reproduction to make copies of itself, which can only happen after they have invaded the cells of another organism. Outside of their host some viruses can still survive, depending on environmental conditions, but their life span is considerably shorter.

Can bacteria live on gold?
This is due to the fact that gold is a chemically inert material, that is, it does not react or change when it comes into contact with an organism. … This new research shows that these chemically inert nanoparticles can kill bacteria thanks to a physical mechanism that deforms the cell wall.
