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."

Creatures at Tama Zoo

Eiffinger's Tree Frog
Kurixalus eiffingeri

They have a strong arboreal habit and are said to be the only frog in Japan that "raises its young", with mother frogs laying their eggs in puddles in tree hollows. Even after the eggs hatch, they occasionally return to lay unfertilized eggs in the puddles, which they then feed to the tadpoles to raise. They make a high-pitched, short chirp, "beep! beep!"

classification	Amphibians, Frogs, Rhacophoridae
English name	Eiffinger's Tree Frog
distribution	Japan (Ishigaki Island, Iriomote Island, Taiwan)
Residence	mountain forests
Size	Body length: 31-40mm
food	Insects, spiders
Red List	IUCN: LC (Least Concern)

form

At first glance, it may give the impression of being similar to Japanese Tree Frog, but it actually belongs to the same family Forest Green Tree Frog, as the Japanese tree frog (Rhacophorus arboreus). It is smaller than other Japanese tree frogs. It has a grayish-brown or brown body color.

Where is he?

Because they are highly arboreal, they are often found on walls and planted plants in the exhibits.
