Zoo Stock Species and the Red List
Zoo Stock Species and the Red List
Zoo Stock
This indicates that the species is included in the Second Zoo Stock Plan, which was formulated by the Tokyo Metropolitan Government in 2018. The plan sets goals for the next 10 years in three areas: "species conservation," "contribution to wildlife conservation," and "environmental education and conservation awareness." 124 animal species are included.
What is the Red List?
Based on scientific research, this is a list of wildlife classified by rank (category) indicating the degree of risk of extinction.
Livng Things Encyclopedia shows the categories (mainland and islands) assessed by the IUCN (International Union for Conservation of Nature) at the global level, the Ministry of the Environment for Japan, and the Tokyo Metropolitan Government for Tokyo.
The higher the category in each table, the higher the risk of extinction, and CR, EN, and VU are the three categories known as "endangered species." In Tokyo, species that are not at the NT (near threatened) level but are relatively rare are considered "species of concern."

Orycteropus afer
Aardvark
Orycteropus afer
Although its name means "Domestic Pig," it has no relation to Domestic Pig at all, and is the only animal in the primitive ungulate order, Tubulodonta. It lacks incisors or canines, and its molars are made up of tubular clusters that continue to grow throughout its life. It is nocturnal, living by digging holes with its strong claws, and licking up ants and termites with its long, sticky tongue. It can walk several kilometers to several tens of kilometers in a night in search of food.
