Facts about the real animal.
01

It lives along the coasts of Hokkaido, Honshu, Kyushu and Okinawa, and from Korea, Taiwan and China to the tropical eastern Indian Ocean and western Pacific.

02

The crown-like knob on its head is low, and it has a spine on its jaw.

03

It lives in seaweed beds and among sea creatures called yagi (gorgonians).

How the Flat-faced seahorse lives

It rapidly sucks in small fish, shrimp and zooplankton to eat. It lives upright, wrapping its finless tail around seaweed and other supports. It can be hard to spot because it resembles seagrass and similar plants.

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.
