Ten of the most endangered species in the world (source http://www.guardian.co.uk/environment/2010/apr/08/barometer-of-life):
Florida bonneted bat – Eumops floridanus was thought to be extinct until 2002, when a small colony was discovered in a North Fort Myers suburb of Florida, US.
Saola – The cow-like Pseudoryx nghetinhensis, which occurs only in the Annamite mountains of Vietnam and Laos is in protracted decline.
Kakapo or owl parrot – In 2008, the total population of this large, flightless nocturnal parrot (Strigops habroptila) from New Zealand was 93, including the seven hatched that year.
Golden arrow poison frog – With the chytridiomycosis epidemic spreading from west to east through Panama, populations of Atelopus zeteki are now at severe risk.
Jamaican iguana – There may be no more than a hundred adult Cyclura collei remaining in the wild, and juvenile recruitment appears to be minimal.
Chinese paddlefish – Only two adult specimens of Psephurus gladius (both females) have been recorded since 2002. It is expected there are fewer than 50 adults left in the wild.
Chinese giant salamander – The largest of all amphibian species, sometimes growing to more than 1m long, Andrias davidianus is widespread in southern China, but its range is very fragmented
Sicilian fir – Abies nebrodensis trees are presently limited to the steep, dry slopes of Mt. Scalone in the Madonie Mountains of Sicily.
Sumatran orang-utan – The majority of surviving Pongo abelii live in the province of Aceh in northern Sumatra, Indonesia.
