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."

Filefish
Psolus fabricii
Filefish
Psolus fabricii
It lives in relatively shallow, sandy areas. Its trademark features are its diamond-shaped body and a single spine on its dorsal fin. The skin of this species is thick and rough like sandpaper, and it is said to have been named "skin-pepper" because it is peeled off when prepared for cooking. It swims by undulating its dorsal and anal fins. It is not a fish that is caught in large quantities, but it is a popular delicacy, enjoyed as sashimi or in liver-based dishes.
