Galápagos tortoise
Turtle can live very long lives; a Galápagos tortoise collected by Charles Darwin in 1835 died in 2006, living for at least 176 years though most wild turtles do not reach that age. Turtles keep growing new scutes under the previous scutes every year, allowing researchers to estimate how long they have lived; they age very slowly. The survival rate for adult turtles can reach 99 percent per year.
