Strange species of almost 'immortal' creatures

Scientists believe that a freshwater invertebrate species may be 'immortal' and some other species will live longer and healthier.

Hydra magnipapillata , a tiny animal with a tubular body consisting of tentacles, sticky mouths and legs, may not be a pet that people can embrace like a dog or a cat, but it completes Full unaffected by the aging process.

Scientists from the University of Southern Denmark have studied the lifespan of 46 different species, including mammals, plants, fungi and algae. While humans, mammals and birds are defined to have short lifespans, other living organizations such as turtles and some plants become healthier when they get older.

'Many people including scientists think that the aging process is inevitable and occurs at all organizations living on Earth. Like humans, other creatures become weaker when they get older and die. This is not the case , "evolutionary biologist Owen Jones said.

Scientists have found that some species can live forever and are not affected by the aging process. Hydra magnipapillata freshwater has extremely low mortality rates and in laboratory conditions, they are almost immortal.

'Speculation from the experimental results shows that even after 1,400 years, 5% of the population of Hydra magnipapillata is kept in laboratory conditions still alive , ' said Dr Jones.

For many species, the mortality rate increases with age and this can be seen in most mammals such as humans and killer whales as well as invertebrates such as fleas. Besides, some other species reduce the risk of death when they are old. For example, desert turtles have the highest risk of death in their early years and decrease as they age.
