Citizen science for seahorse conservation

Through iSeahorse, our pioneering citizen science program, Project Seahorse is creating a global network for seahorse science and conservation. iSeahorse is a website and smartphone app that allows anyone, anywhere in the world to contribute to seahorse science and conservation. Follow the links or scroll down to learn how you can share your seahorse observations and help protect threatened populations.

How iSeahorse works

Anyone can join

Whether you’re a diver, a fisher, a scientist, a seahorse enthusiast, or just on a beach holiday, you can share your wild seahorse sightings with a click of a mouse or tap on a smartphone. 

Join to upload your seahorse observations and photos, help us identify species, and learn how you can advocate for their protection in your ocean neighbourhood.

Turning your data into conservation action

Scientists from Project Seahorse and seahorse experts around the world will use your vital information to better understand seahorse behaviour, species ranges, and the threats seahorses face. Together, we'll use this knowledge to mobilize governments, policy makers, and ocean advocates to protect seahorses and their ocean ecosystems.

Population monitoring

Do you dive regularly in areas where there are seahorses, or live or work near a fishing port? We're also looking for people who can help with tracking wild seahorse populations over longer periods of time. A background in marine science, conservation, or fisheries is useful, but not strictly necessary.

What iSeahorse does

New scientific discoveries

By turning divers, snorkelers, photographers, tourists, and others into citizen scientists, iSeahorse expands the number of people studying seahorses around the world from fewer than 20 scientists to hundreds and even thousands of citizen scientists.

A global early warning system for seahorses

iSeahorse generates seahorse population monitoring projects around the world. This growing network is poised to sound the alarm whenever and wherever seahorses and their habitats are under threat.  

From citizen science to 'citizen conservation'

The ultimate goal of iSeahorse is to turn citizen scientists into 'citizen conservationists' — we give you the data and the tools you need to advocate for seahorse populations at the local, national, regional, and global level.
