Facts about the real animal.
01

A small jellyfish found in the seas of northern Japan.

02

In its polyp stage, it lives together with a bristle worm called erako, on the worm's tube.

03

Its polyp is well known as the ningyou-hydra.

How the Proboscidactyla flavicirrata lives

The polyps stretch out long tentacles to take food from bristle worms. They also eat eggs released by that bristle worm. As the tube grows longer, the colony extends so its feeding polyps stay at the opening. Jellyfish bud from the polyp colony and are released.

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.
