The turritopsis nutricula species of jellyfish may be the only animal in the world to have truly discovered the fountain of youth.
Since it is capable of cycling from a mature adult stage to an immature polyp stage and back again, there may be no natural limit to its life span. Scientists say the hydrozoan jellyfish is the only known animal that can repeatedly turn back the hands of time and revert to its polyp state (its first stage of life).
The key lies in a process called transdifferentiation, where one type of cell is transformed into another type of cell. Some animals can undergo limited transdifferentiation and regenerate organs, such as salamanders, which can regrow limbs. Turritopsi nutricula, on the other hand, can regenerate its entire body over and over again. Researchers are studying the jellyfish to discover how it is able to reverse its aging process.

The world’s only pink Bottlenose dolphin which was discovered in an inland lake in Louisiana, USA, has become such an attraction that conservationists have warned tourists to leave it alone. Charter boat captain Erik Rue, 42, photographed the animal, which is actually an albino, when he began studying it after the mammal first surfaced in Lake Calcasieu, an inland saltwater estuary, north of the Gulf of Mexico in southwestern USA.
