Sources and how we check

We check each fact against its source. The illustrations simplify how the real animal looks.

The classification (class, order, family, genus) follows Wikidata records, checked against GBIF. Classifications can change as research goes on.

The basic data are the values given in each source. They vary with how the animal is measured, whether it is male or female, and whether it lives in the wild or in captivity.

The conservation status in Japan is the category in the Red Lists of the Ministry of the Environment of Japan, which assess the risk of extinction for wild animals in Japan.
