Why seahorses?

A mysterious and charismatic species under threat

Every year, millions of seahorses are caught and traded, dead and alive, all over the world. They are displayed in aquariums, used as ingredients in traditional Chinese medicine, and turned into curios.

According to the IUCN Red List, nine seahorses species are Vulnerable and one is Endangered, but 28 other seahorse species are listed as Data Deficient. This means we do not know enough about them to assess their conservation status.

Based on our research, we know that seahorses are vulnerable to overfishing and habitat damage. However, seahorses are difficult to study in the wild because of their ability to blend, chameleon-like, into their surroundings, and their near-global geographical range.

We need more information, and you can help. Record your seahorse observations, help identify a seahorse, or check out our advocacy page.

The case for seahorse conservation

Seahorses are flagship species, charismatic symbols of the seagrasses, mangroves, coral reefs, estuaries and seaweeds where they make their homes.

Seahorses need to be protected for ecological, biological, economic, and medical reasons. They are important predators on bottom-dwelling organisms; removing them may disrupt ecosystems.

Only the male becomes pregnant and many seahorse species are mate for life. Their unusual life history provides us with an opportunity to expand our understanding of reproductive ecology.
