• Ubiquitous perchlet (Plectranthias 'ubiquitous')
• French butterflyfish (Prognathodes guyanensis)
• Tibetan brown bear (Ursus arctos pruinosus)

The Tibetan brown bear (Ursus arctos pruinosus) is endemic to the Tibetan Plateau in Asia and is so rarely seen in the wild that it played a part as inspiration for the yeti.

The Chinese bamboo rat (Rhizomys sinensis) is despite heavy farm breeding activities in China rarely seen in captivity outside the country. 

The Coral Sea mask ray (Neotrygon trigonoides) was not known to be kept in captivity until I discovered this specimen in the Osaka Aquarium in Japan.
