A seahorse that often stays very small even when fully grown.

How the Dwarf seahorse lives

It anchors itself with its tail and blends into its surroundings while waiting for prey. It stretches toward its prey and sucks it in through its snout. It swims upright using its dorsal fin and steers with its pectoral fins. It generally lives alone or in pairs.

Where the Dwarf seahorse has been recorded

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.
