Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically.

Johora Singaporensis
''Johora singaporensis'', the ''Singapore stream crab'' or ''Singapore freshwater crab'', is a critically endangered species of freshwater crab endemic to Singapore. It grows to a size of wide. Ecology ''J. singaporensis'' lives in streams running through undisturbed forest, where it hides under rocks at the stream's edge, or inside aggregations of leaves and detritus. It is mostly nocturnal, feeding on detritus and oligochaete worms which live in the muddy stream bed. Distribution ''J. singaporensis'' only lives in Singapore, and has only ever been recorded from two locations. One of these was inside Bukit Timah Nature Reserve, but that population is believed to have been extirpated, as recent surveys have failed to find any examples there. The second population is outside the nature reserve at Bukit Batok, partly on private land, and partly on military land. Acidification of the first stream may have caused the first population to die out, while a lowering of the water ...
