7 de abr. de 2020 · Normally speaking we expect very few individuals in a natural population to reach their maximum age. So age estimates of wild-caught or killed animals are usually considered to be below the maximum. Biologists have a number of ways of aging animals. The techniques vary with different species and have lesser or greater degrees of ...

- Giant Barrel Sponge
The deep-sea tube worm, also known as Riftia pachyptila, lives until about 250 years old, though in some cases this can stretch much further. Amazingly, they have no digestive system, mouth, or anus, and thus do not consume food to survive in a traditional sense. Instead, the bacteria living inside their bodies helps to transform the sulfur from ne...
The immortal jellyfish, otherwise known as Turritopsis dohrnii, is biologically immortal. How is this possible? Essentially, these creatures revert and transition backwards from sexual maturity towards sexual immaturity in a process called transdifferentiation—where adult cells are converted into other types of tissue. Not surprisingly, processes l...
The giant barrel sponge can live for 2,300 years. These cool creatures live on the reef surface of the ocean, and are bowl shaped, which provides habitat for many other invertebrates including crabs, shrimps, as well as fish. In addition, spongeshave no tissue and each of their individual cells can do the same job of any other cell. Some experiment...

Life span - Animal Longevity, Aging, Adaptations: Much of what is known of the length of life of animals other than man derives from observations of domesticated species in laboratories and zoos. One has only to consider how few animals reveal their age to appreciate the difficulties involved in answering the apparently simple question of how ...

Maximum life span (or, for humans, maximum reported age at death) is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death. The term can also denote an estimate of the maximum amount of time that a member of a given species could survive between birth and death ...
21 de fev. de 2023 · For an animal or human to be considered old, you must first understand its average lifespan. Each animal and human have a certain life expectancy , an expected age for the species to live. The average lifespan will vary from days to months, to years, as an expectancy of how long the particular animal or person will be alive .
