The Galápagos tortoise or Galápagos giant tortoise is the largest living species of tortoise and the 13th-heaviest living reptile. With life spans in the wild of over 100 years, it is one of the longest-lived vertebrates. A captive individual lived at least 170 years. It is native to seven of the Galápagos Islands, Ecuador. by Arthur Morris
Even though River Otters are not listed as Endangered species, their range has been greatly reduced over the years by habitat destruction and they are vulnerable to pollution and toxins in the environment.
