Some tortoises show negligible senescence. Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. [1]
There are numerous plants and animals for which the mortality rate has been observed to actually decrease with age, for all or part of the life cycle. [2] Hydra were observed for four years without any increase in mortality rate. [3] If the mortality rate remains constant, the rate determines the mean lifespan.
According to the Animal Aging and Longevity Database, the list of animals with negligible aging (along with estimated longevity in the wild) includes: [12] Blanding's turtle (Emydoidea blandingii) – 77 years; Olm (Proteus anguinus) – 102 years; Eastern box turtle (Terrapene carolina) – 138 years
Turtles seem to have survived the mass extinctions of the prehistoric eras, likely due to their slow metabolisms (they can go some time without food), aquatic lifestyles and protective shells. 23 ...
The average life span of adult box turtles is 50 years, while a significant portion lives over 100 years. The age of a growing box turtle in the wild cannot be accurately estimated by counting the growth rings on the scutes ; Their growth is directly affected by the amount of food, types of food, water, illness, and more.
In the United States, around 2.3 million households are home to reptiles, including turtles. Here's what the reptile can and cannot eat.
Turtles are facing a population crisis having to do with human impact. On Tuesday, the Protect Sea Turtles Forever stamps were announced at a dedication ceremony held at the Texas State Aquarium ...
Most sea turtle mortality happens early in life. Sea turtles usually lay around 100 eggs at a time, but on average only one of the eggs from the nest will survive to adulthood. [135] Raccoons, foxes, and seabirds may raid nests or hatchlings may be eaten within minutes of hatching as they make their initial run for the ocean. [136]
