From the 2012 WWF's List of Endangered Animals
The Javan Rhinoceros (Rhinoceros sondaicus)
Is very close to extinction. There are believed to be as few as 40 left in the wild in Ujung Kulon National Park, Indonesia and none are currently in captivity. The IUCN Red List currently lists Javan rhinos as critically endangered.
In October, poachers killed the last remaining Javan rhino in Vietnam. Several were alive in the wild in Vietnam as recently as 2004.
A survey of surviving Javan rhinos in Indonesia found that there are very few females in the population.
There are 4,080 to 6,590 of this Magnificent animal left in the wild
The Irrawaddy dolpin (Orcaella brevirostris)
According to WWF, there are only 85 of these dolphins left in Southeast Asia. The limited range of this animal along with killing by fisherman has left Irrawaddy dolphin populations in danger.
The Vaquita (Phocoena sinus)
WWF estimates that there are around 245 vaquita left in the wild. They are most immediately threatened by “entanglement in fishing gear.” Fortunately, WWF helped authorities in Mexico to reduce bycatch of vaquita to a “level that does not threaten the population” by 2009.
Armed conflicts and natural resource exploitation have been blamed for endangering the gorilla populations.
Their wide geographical distribution and shallow dive depth means they are threatened by longline fishing operations, explains WWF.
A study from September found that although the number of sea turtles killed in U.S. fisheries has declined by 90 percent since 1990, it may not be enough to sustain sea turtle populations.
In August, a 700-pound leatherback washed up on the shore at Montauk, New York.
According to WWF, they are the most endangered of the two orangutan species and there are about 7,500 Sumatran Orangutans left in the wild.
Native only to parts of Sumatra, Indonesia, the orangutans are threatened by human agricultural and residential development.
A recent study found that residents of Borneo killed at least 750 endangered orangutans in a one-year period.
World Wildlife Fund estimates that there are between 41,410 and 52,345 Asian elephants in the wild.
HuffPost blogger Wendy Diamond writes that besides deforestation and industrialization, landmines also threaten Asian elephants in the wild. The founder of an elephant park in Thailand claims he “has known about 20 elephants who stepped on land mines and died” since 1989. Efforts to raise awareness for elephants’ fragile status include Elephant Appreciation Day.
