Orchids (Cypripedium calceolus, Cypripedium parviflorum) Background info: Dendrobium thyrsiflorum, Dendrobium unicum Many species of orchids, mostly located in tropical areas have disappeared or are threatened.

Turtles (Centrochelys sulcata) Background info: Astrochelys radiate They are traditionally divided into three groups: tortoises, aquatic turtles, or freshwater turtles, and sea turtles.
