Collectively, Cercocebus and Mandrillus include nine species and two subspecies of African monkeys: seven species of Cercocebus and two of Mandrillus, including two drill subspecies. Together, they represent some of the least studied and hence least known of the Afro-Eurasian Primates.
Distributed in the Sundaland region (Thai-Malay Peninsula, Sumatra, Borneo, Java and adjacent smaller islands), langurs of the genus Presbytis are one of the most threatened groups of Asian primates. According to the IUCN Red List of Threatened Species, 24 of the 28 taxa (>85%) are threatened with extinction (listed as Critically Endangered, Endangered or Vulnerable). One taxon is classified as Near Threatened and one as Data Deficient. Only two Presbytis taxa are considered as Least Concern.
As the most threatened vertebrate class on earth, amphibians are at the forefront of the biodiversity crisis, with the recognition of global amphibian declines and extinctions dating back several decades now.
The Galápagos pink land iguana (Conolophus marthae) is categorised as Critically Endangered. The entire distribution of pink iguanas is within the protected area of the Galápagos National Park (GNP), which is managed by the Galápagos National Park Directorate (GNPD). This conservation and management plan (2022–2027) has the vision to ensure the long-term survival of Galápagos pink land iguanas in the wild, and as a general objective to establish a comprehensive conservation programme for Galápagos pink land iguanas that facilitates their recovery and persistence in the wild.
La iguana rosada de Galápagos (Conolophus marthae) está clasificada como En Peligro Crítico de Extinción.
The golden monkey, Cercopithecus mitis kandti, an Endangered subspecies of blue monkey, is found in only two small populations in the central part of the Albertine Rift region in Central/East Africa. Since the 1950s, the habitat of golden monkeys has been lost or degraded in the Virunga massif (Democratic Republic of the Congo, Rwanda, Uganda), including a reduction of approximately 50% in the Volcanoes National Park (VNP), the Rwandan part of the Virunga massif, and by a staggering 98% in the Gishwati forest located in Rwanda.
Ranging from forests in Senegal to the Zanzibar Archipelago, red colobus monkeys (Piliocolobus spp.) are the most threatened group of African monkeys. According to the IUCN Red List of Threatened SpeciesTM in 2020, every form of red colobus monkey is threatened with extinction, and 14 of the 18 taxa (>75%) are listed as Critically Endangered or Endangered. Despite their conservation status, only a few populations have been studied in any detail and the general public is largely unaware of these monkeys and their plight.
China’s Yangtze river dolphin (Lipotes vexillifer), was declared likely to be extinct in 2006, due to threats in the wild such as habitat loss, entanglement in fishing gear and ship strikes, which were not effectively dealt with using the management tools available prior to that time. Mexico’s vaquita (Phocoena sinus), a porpoise found only in the Upper Gulf of California, will become extinct in the near future if the illegal fishery to obtain fish swim bladders for illicit international markets is not eliminated very soon.
