Rhinoceros
The rhinoceros is a magnificent animal, but three of the five species, the Javan, Sumatran and black rhinos, are critically endangered. Rhinos are threatened by poaching and habitat loss. The white rhino was nearing extinction and has been brought back from the brink through sustained conservation, and groups such as Sumatran Rhino Rescue are working to save the rarest species.
River sharks
Glyphis river sharks live in tidal rivers, estuaries and coastal waters of South and Southeast Asia, New Guinea and northern Australia. They are among the least-known sharks in the world. The Ganges shark is listed as Critically Endangered and the speartooth shark as Vulnerable on the IUCN Red List. Their main threats are fishing bycatch and the degradation of the river habitats they depend on.
