Eastern gorilla
The eastern gorilla ("Gorilla beringei") is a critically endangered species of the genus "Gorilla" and the largest living primate. At present, the species is subdivided into two subspecies. Grauer's gorilla, formerly known as the eastern lowland gorilla ("G. b. graueri") is more populous, at about 3,800 individuals. The mountain gorilla ("G. b. beringei") has only about 1000 individuals. The International Union for the Conservation of Nature mentioned illegal hunting in its assessment of threats to the species.
Sauropoda
The best evidence indicates that the most massive were "Argentinosaurus" (120 metric tons), "Puertasaurus" (80 to 100 metric tons ), "Alamosaurus", "Paralititan", "Antarctosaurus" (69 metric tons). There was poor (and now missing) evidence that so-called "Bruhathkayosaurus", might have weighed over 175 metric tons but this has been questioned. The weight of "Amphicoelias fragillimus" was estimated at 122.4 metric tons but 2015 research argued that these estimates may have been highly exaggerated. The largest land animal alive today, the Savannah elephant, weighs no more than .
