Facts about the real animal.
01

A fish that lives mainly in lowland rice paddies, wetlands and the small streams around them.

02

Besides breathing with its gills, it is said to also breathe air using its intestine.

03

When water is let into the rice paddies and the soil is churned up, it moves from the channels into the paddies and lays its eggs at night.

How the Pond loach lives

They eat animals such as midge larvae. The eggs are scattered over the mud. After spawning, adults and newly hatched young live in the rice paddy.

Each dot marks a place with observations or specimens shared on GBIF. Some records are of animals that strayed or were brought by people, so the dots are not always where the animal lives.

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.
