Green turtle
Green turtles are listed in the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). Although 58 countries have helped to protect the green turtle by joining an international convention controlling the import, export, and use of endangered species, the demand for turtle soup, "turtle oil" for cosmetics, and turtle skin for shoe leather has encouraged a continuing, and often illegal, trade.

Crested Iguana
A zookeeper holds a Fijian Crested Iguana at Taronga Zoo in Sydney during an announcement of a funding boost for their conservation. Only a few wild populations remain of the endangered iguana which is found on Fijian islands. The species faces possible extinction due to habitat destruction and competition from introduced species.

Cottontop Tamarin
The cottontop tamarin (Saguinus oedipus) is one of the most endangered primates in the world. It is estimated that there are less than 1,000 of such primates in the wild and about 1,800 in captivity. Life span in captivity has been as high as 25 years whereas life span in the wild is about 13–16 years. They are now protected by international law; although they are numerous in captivity, they are still critically endangered in the wild.

Corroboree Frog
The Corroboree Frog is one of Australia's most endangered species, with fewer than 200 of the frogs existing in the wild. The decline of Corroboree Frogs, and many other frog species throughout Australia, is mainly due to a disease known as chytridiomycosis, which is caused by infection with the Amphibian Chytrid Fungus (Batrachochytrium dendrobatidis).

Grevy's Zebra
Grevy's zebra is listed as an endangered species with only 1,500 to 2,000 remaining in the wild. Hunting and competition from livestock have greatly decreased their population. Because of the population's small size, environmental hazards, such as drought, are capable of easily affecting the entire species.
